Solution by Steps
step 1
To solve the quadratic equation x22x35=0x^2 - 2x - 35 = 0, we look for factors of -35 that add up to -2
step 2
The factors of -35 that add up to -2 are -7 and 5
step 3
We rewrite the quadratic equation as (x7)(x+5)=0(x - 7)(x + 5) = 0
step 4
Set each factor equal to zero: x7=0x - 7 = 0 or x+5=0x + 5 = 0
step 5
Solve for xx in each equation: x=7x = 7 or x=5x = -5
Answer
lesser x=x= 5-5
greater x=x= 77
Key Concept
Factoring a quadratic equation
Explanation
To solve a quadratic equation by factoring, we find two numbers that multiply to the constant term (-35) and add to the linear coefficient (-2). We then set each factor equal to zero and solve for xx.
