Answer: -7, 12

Step-by-step explanation:

a+b = 5

a*b = -84

a = 5-b

(5-b)*b = -84

-b^2 + 5b + 84 = 0

(-b - 7)(b + 12) = 0

The roots are -7 and 12.

In order to simplify this expression, we need to multiply the numeric values together and the variables together.

So we have:

$\begin{gathered} 12x\cdot3x\\ \\ =(12\cdot3)\cdot(x\cdot x)\\ \\ =36x^2 \end{gathered}$

Therefore the correct option is the third one.
