Answer:

4x^2 -16

Step-by-step explanation:

(2x + 4)(2x - 4)

FOIL

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

outer: -4 *2x = -8x

inner: 4*2x = 8x

last: -4*4 = -16

Add them together

4x^2 -8x+8x =-16

4x^2 -16

Factor the GCF out of the trinomial on the left side of the equation. (2 points: 1 for the GCF, 1 for the trinomial)2x^2 + 6x -

iren2701 [21]

Answer:

2(x+6)(x-3)

Step-by-step explanation:

Factor the GCF out of the trinomial on the left side of the equation.

$2x^2 + 6x - 36 =2(x^2 + 3x - 18)$

Greatest common factor of 2, 6, 18 is 2

so GCF is 2

divide each term when we take out GCF 2

so $2(x^2 + 3x - 18)$

now factor the trinomial

product is -18 and sum is +3

6 times -3 is -18 and 6-3=3

$2(x^2+3x-18)\\2(x+6)(x-3)$
