Question

Simplify.12x • 3x15 x15 x236 x236 x

Answer 1

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.
