Question

What is the product of (4x + 3)(-2x - 5)?

A) -8x^2 - 26x - 15

B) -8x^2 + 26x - 15

C) -8x^2 - 26x + 15

Answer 1

A) -8x^2 - 26x - 15

Explanation:

(4x + 3)(-2x - 5)

FOIL

first: 4x*-2x = -8x^2

outer : -5*4x = -20x

inner: -2x*3 = -6x

last: -5*3 = -15

Add these together

-8x^2 -20x-6x -15

-8x^2 -26x-15
