Answer:

D

Step-by-step explanation:

So we have the expression:

[tex](6m+3)(m-2)[/tex]

Use the distributive property and distribute:

[tex]=(6m+3)(m)+(6m+3)(-2)[/tex]

Distribute:

[tex]=(6m^2+3m)+(-12m-6)[/tex]

Combine like terms:

[tex]=6m^2+3m-12m-6\\=6m^2-9m-6[/tex]

The correct answer is D
