\left(x^{2}-4x\right)\left(x+2\right)
Use the distributive property to multiply x by x-4.
x^{3}+2x^{2}-4x^{2}-8x
Apply the distributive property by multiplying each term of x^{2}-4x by each term of x+2.
x^{3}-2x^{2}-8x
Combine 2x^{2} and -4x^{2} to get -2x^{2}.
\left(x^{2}-4x\right)\left(x+2\right)
Use the distributive property to multiply x by x-4.
x^{3}+2x^{2}-4x^{2}-8x
Apply the distributive property by multiplying each term of x^{2}-4x by each term of x+2.
x^{3}-2x^{2}-8x
Combine 2x^{2} and -4x^{2} to get -2x^{2}.
