Answer 1

Answer:

B

Step-by-step explanation:

start by multiplying the 6a to each number in the other set of parenthesis.

after doing so, you end up with the numbers: $12a^{2}$ and $-54a$

now multiply the one to each number in the other parenthesis. you get this:

$2a$ and $-9$.

then set it all next to each other: $12a^{2}$$-54a$+$2a$$-9$

then combine like terms (-54a and 2a) you get: $12a^{2} -52a-9$

so that is how you get B for the answer
