Answer:

x^3 + 9x^3 -6x -54

Step-by-step explanation:

first step is you're going to simplify the problem.

using the (a-b)(a+b)=a^2-b^2 formula combine the last two grouped numbers to equal (x+9)(x^2-6)

multiply the parenthesis to get x^3 - 6x + 9x^2 -54

reorder the terms and then you get your answer! x^3 + 9x^3 -6x -54

does this make sense? :)
