Question 209557
{{{2x^5 + x^4 - 8x^3 - 4x^2}}}

{{{x^2(2x^3 + x^2 - 8x - 4)}}} ------ Factor out GCF, {{{x^2}}}

{{{x^2(x^2(2x + 1) - 4(2x + 1))}}} ------ Factor the inner polynomial


Therefore, we have: {{{x^2(x^2 - 4)(2x + 1)}}}


Factor {{{x^2  - 4}}} to get: {{{highlight_green(x^2(x - 2)(x + 2)(2x + 1))}}}
