Answer:

#36x#

Explanation:

To solve, all you have to do is simplify.

Let's start piece by piece by looking at the coefficients of the numbers in the parenthesis,

which are #-6# and #-4# in #-6(-2x) * -4(-6x)#

We'll distribute the coefficients, aka multiplying the #-6# with the #(-2x)# and the #-4# with the #(-6x)#:

  • #-6*(-2x)=12x#
  • #-4*(-6x)=24x#

You only multiply the coefficients together, you leave x alone because it's an unknown variable.
Multiplying two negatives together leaves you with a positive answer.

Keep simplifying by combining like terms: #12x+24x#

Which equals your answer, #36x#.
