Question

( 6m + 3 )( m - 2 ) A) 4m 2 - 2m - 20 B) 4m 2 - 20 C) 4m 2 + 18m + 20 D) 6m 2 - 9m - 6

Answer 1

Answer:

D

Step-by-step explanation:

So we have the expression:

$(6m+3)(m-2)$

Use the distributive property and distribute:

$=(6m+3)(m)+(6m+3)(-2)$

Distribute:

$=(6m^2+3m)+(-12m-6)$

Combine like terms:

$=6m^2+3m-12m-6\\=6m^2-9m-6$

The correct answer is D
