Problem
Find the area enclosed between y = x² and y = 2x in the first quadrant.
1
Find the points of intersection
Set the curves equal: x² = 2x → x(x - 2) = 0, so x = 0 and x = 2.
2
Identify which curve is on top
On (0, 2), 2x > x², so y = 2x is the upper curve.
3
Set up the area integral
A = ∫₀² (2x - x²) dx
4
Integrate term-by-term
A = [ x² - x³/3 ]₀²
Final Answer
A = 4/3 sq. units
Quick Answer
What is the AskSia polynomial long division solver?
The AskSia polynomial long division solver divides any polynomial by another using the long division layout step-by-step, just like integer long division. The four-step cycle: divide the leading term of the current dividend by the leading term of the divisor (giving the next quotient term), multiply the divisor by that quotient term, subtract from the current dividend, and bring down the next term from the original dividend. Repeat until the current dividend has lower degree than the divisor. Works for any divisor (linear, quadratic, cubic), unlike synthetic division which only works for linear divisors.

Why AskSia Solver
Long division for polynomials. Every step shown.
Divide leading terms, multiply back, subtract, bring down. Repeat until the remainder has lower degree than the divisor. AskSia shows the full layout.
Four-step cycle: divide, multiply, subtract, bring down
Each cycle: divide the leading term of the current dividend by the leading term of the divisor (giving the next quotient term), multiply the entire divisor by that quotient term, subtract from the current dividend (aligning by power), bring down the next term.
Cycle named
Any divisor, not just linear
Polynomial long division works for divisors of any degree (linear, quadratic, cubic, higher). Synthetic division only works for linear divisors of the form (x minus c), so long division is more general.
Any divisor
Placeholder zeros for missing terms
When the dividend has missing terms (like x³ + 5 with no x² or x term), AskSia inserts placeholder zeros (x³ + 0x² + 0x + 5) to keep the powers aligned during subtraction. The placeholders are shown explicitly.
Placeholders
Quotient and remainder reported
The final answer has the form (quotient) + (remainder)/(divisor). AskSia reports both explicitly. If the remainder is zero, AskSia notes that the divisor is a factor of the dividend.
Quotient + remainder
Synthetic comparison when applicable
When the divisor is linear (of the form x minus c), AskSia notes that synthetic division would also work and shows both layouts side-by-side if requested. Useful for understanding why synthetic is faster.

Watch the long division layout
AskSia fills in the layout step-by-step: divide leading terms, multiply back, subtract, bring down. Each cycle is labeled, so the structure is visible.
1
Set curves equal
x² = 2x → x = 0, x = 2
2
Set up the integral
A = ∫₀² (2x - x²) dx
3
Evaluate
A = [x² - x³/3]₀² = 4/3
Step 03
See quotient and remainder
The final answer has the form quotient + remainder/divisor. If the remainder is zero, AskSia notes that the divisor is a factor.

Use Cases
Every polynomial division use case.
Algebra 2 introduction
First-time polynomial long division problems with simple linear or quadratic divisors. AskSia shows the layout clearly and explains each move in the cycle.
Algebra 2
Quadratic and higher divisors
Long division by quadratic or cubic divisors, where synthetic division does not apply. AskSia handles any divisor degree.
Higher divisors
Factor checking
To check whether one polynomial is a factor of another, divide and see if the remainder is zero. AskSia reports the result and notes the factor relationship.
Factor check
Reducing polynomial fractions
To rewrite (x⁴ + 3x³ + ...)/(x² + 1) in 'quotient + remainder/divisor' form, AskSia performs long division and reports the result in proper rational form.
Proper rational
Calculus prep: oblique asymptotes
When the degree of numerator exceeds degree of denominator by 1, polynomial long division finds the slant (oblique) asymptote of a rational function. AskSia handles this directly.
Oblique asymptote
Compare to synthetic
When the divisor is linear, both long division and synthetic division work. AskSia can show both layouts to make the connection clear.

FAQ
Frequently asked questions.
How does polynomial long division work step-by-step?
Polynomial long division follows the same four-step cycle as integer long division. Step 1: divide the leading term of the current dividend by the leading term of the divisor; the result is the next term of the quotient. Step 2: multiply the entire divisor by that quotient term. Step 3: subtract the result from the current dividend (line up terms by power). Step 4: bring down the next term from the original dividend (if any). Repeat until the current dividend has lower degree than the divisor; what's left is the remainder. AskSia shows every step in the textbook bracket layout.
When should I use long division instead of synthetic division?
Use synthetic division when the divisor is linear and of the form (x minus c), where c is a constant. It's faster and uses just the coefficients, not the full polynomials. Use long division for any other divisor: linear with non-leading coefficient ≠ 1 (like 2x + 3), quadratic divisors (like x² + 1), cubic divisors, or any higher degree. Long division always works; synthetic only works for the special linear case. AskSia picks automatically: synthetic when applicable for speed, long division otherwise.
What if the dividend has missing terms (like no x² term)?
AskSia inserts placeholder zeros to keep the powers aligned during subtraction. For example, to divide x³ + 5 by x minus 2, AskSia rewrites the dividend as x³ + 0x² + 0x + 5 so the long division aligns terms correctly during each subtraction step. Without the placeholders, the subtraction would shift terms into the wrong column and produce errors. The placeholders are shown explicitly in the layout.
How do I know when polynomial long division is done?
Long division is done when the current dividend (what's left after the most recent subtraction) has lower degree than the divisor. At that point, you can't divide further, and the current dividend becomes the remainder. The result is reported as quotient + remainder/divisor. If the remainder is zero, the divisor is a factor of the original dividend. For example, dividing x² + 5x + 6 by x + 2 gives quotient x + 3 with remainder 0, confirming that x + 2 is a factor.
How accurate is AskSia?
AskSia hits 98% accuracy on standard high school and college coursework, measurably higher than ChatGPT, Photomath, and Symbolab on the same problem sets. Accuracy comes from subject-specialized models, a symbolic verification pass that catches arithmetic errors, and a self-check step that re-derives the answer before showing it to you.
Can I get practice problems and flashcards?
Yes. After any solve, ask Sia to generate similar practice problems at SAT, ACT, AP, IB, or college difficulty, or build a flashcard set on the underlying concept in one tap. Useful for exam prep and spaced repetition before a quiz, midterm, or final.
How much does AskSia cost?
AskSia has a free plan that includes daily solves across all subjects. AskSia Pro and Super include unlimited solves, advanced subjects, the full AI tutor companion, exports, and priority response speed. See pricing for details.
