Question

Use FOIL to multiply.
(3x - 7)(x + 5)

Answer 1

3x²+8x-35

Explanation:

FOIL stands for:

First -> (3x-7)(x+5)

Outer -> (3x-7)(x+5)

Inner -> (3x-7)(x+5)

Last -> (3x-7)(x+5)

Following FOIL, we get:

(3x-7)(x+5)

(3x)(x)+(3x)(5)+(-7)(x)+(-7)(5)

3x²+15x-7x-35

3x²+8x-35

Therefore, the expanded form is 3x²+8x-35

Answer 2

3x^2-7x+15x-35
=3x^2+8x-35
