OPEN ENDED QUESTION
What is our final step for getting x by itself?

Do the opposite operation

Step-by-step explanation:

If there is a coefficient like 3x, you have to divide the 3 on both sides. This is because 3x is equivalent to 3*x. The opposite of multiplication is division.

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
