Question 480903


{{{5x^4 -45x^3 + 25x^2}}}...factor out {{{5x^2}}}-common factor for all three terms


{{{5x^2(x^2 -9x + 5)}}}

{{{5x^2(x^2 -9x + 5)}}}..now try to factor {{{x^2 -9x + 5}}}

*[invoke factoring_quadratics 1, -9, 5]

as you can see, {{{x^2 -9x + 5}}} cannot be factored; so, your solution is:

{{{5x^2(x^2 -9x + 5)}}}
