Question

!28 POINTS! I need help quick!! The area of a rectangle is 2x^2-7x-15. Determine binomials that represent the length and the width if this triangle.

Answer 1

(2x +3 )(x-5)

one is the length and one is the width

Explanation:

2x^2-7x-15

Factor

(2x )(x )

What are the factors of -15? -1*15 and -3*5, 3*-5 , 1*-15

We need 2* one factor ± the other factor = -7

2*-5 +3 = -7

That means the -5 is on the outside and the +3 is on the inside

(2x +3 )(x-5)
