Question

Plz HURRY!!!!!

(2x - 3) and (x + 5) are the factors of a quadratic equation. Write the equation.

A) y = 2x2 + 2x - 15
B) y = 2x2 + 7x - 15
C) y = 2x2 + 7x +15
D) y = x2 + 7x - 15

Answer 1

The answer would be B, 2x2+7x-15.

Explanation:

Use the distributive property!!

(2x-3)(x+5)

distribute the 2x to the x and 5.

You get 2x2+10x

distribute the -3 to the x and 5.

You get -3x-15

combine like terms:

2x2+10x-3x-15

You get the answer 2x2+7x-15

hope this helps :)
