-3x^{4}-x^{2}+8x^{3}+4x-x^{3}+x^{2}
Combine -5x^{4} and 2x^{4} to get -3x^{4}.
-3x^{4}-x^{2}+7x^{3}+4x+x^{2}
Combine 8x^{3} and -x^{3} to get 7x^{3}.
-3x^{4}+7x^{3}+4x
Combine -x^{2} and x^{2} to get 0.
x\left(-5x^{3}-x+8x^{2}+4+2x^{3}-x^{2}+x\right)
Factor out x. Polynomial -3x^{3}+7x^{2}+4 is not factored since it does not have any rational roots.
