Answer:

$-2x^{2} -7x-6$

Step-by-step explanation:

(2x + 3) (-x - 2)

2x(-x) + 2x(-2) + 3(-x) + 3(-2)

multiply:

$(-2x^{2})$ + (-4x) + (-3x) + (-6)

$-2x^{2} -4x-3x-6$

combine the like terms:

$-2x^{2}$ - 4x - 3x - 6

-7x

$-2x^{2}$ - 7x - 6

final answer :

$-2x^{2}$ - 7x - 6

My first reasoning is the fact that the main number is 2
2nd reasoning is that
2 x n = 4
then 4 - 2 = 2
2 + 2 = 4
4 is a factor of 2
