Multiply
-72x^2 - 120x^3 - 36x or in order,
-120x^3 - 72x^2 - 36x

You distribute (multiply) your 12x with everything in parentheses
So you are going to do 12x*-6x 12x*-10x^2 12x*-3
This is going to give you -72x^2-120x^3-36x
If you want, you put it in standard form which is putting the numbers in greatest to least order based on the variables exponent.
YOur final answer is -120x^3-72x^2-36x

72x-120x^3-36x. Because there are different unknowns in the bracket which cannot be solved, you would have to multiply them one by one with the number outside one by one separately.
I hope this helps..;)

12x*-6x + 12x*-10x^2 + 12x*-3
72x^2 - 10x^3 - 36x
