x\left(x^{3}+3x-8x^{2}-24\right)
Factor out x.
x\left(x^{2}+3\right)-8\left(x^{2}+3\right)
Consider x^{3}+3x-8x^{2}-24. Do the grouping x^{3}+3x-8x^{2}-24=\left(x^{3}+3x\right)+\left(-8x^{2}-24\right), and factor out x in the first and -8 in the second group.
\left(x^{2}+3\right)\left(x-8\right)
Factor out common term x^{2}+3 by using distributive property.
x\left(x^{2}+3\right)\left(x-8\right)
Rewrite the complete factored expression. Polynomial x^{2}+3 is not factored since it does not have any rational roots.
