4\left(x^{3}-30x^{2}+225x\right)
Factor out 4.
x\left(x^{2}-30x+225\right)
Consider x^{3}-30x^{2}+225x. Factor out x.
\left(x-15\right)^{2}
Consider x^{2}-30x+225. Use the perfect square formula, a^{2}-2ab+b^{2}=\left(a-b\right)^{2}, where a=x and b=15.
4x\left(x-15\right)^{2}
Rewrite the complete factored expression.
