Question 112193
{{{2z^3+14z^2-60z}}} Start with the given expression



{{{2z(z^2+7z-30)}}} Factor out the GCF {{{2z}}}



Now let's focus on the inner expression {{{z^2+7z-30}}}



*[invoke change_this_name4450 1, 7, -30, "z"]



{{{2z(z+10)(z-3)}}} Now replace {{{z^2+7z-30}}} with {{{(z+10)(z-3)}}}



So {{{2z^3+14z^2-60z}}} factors to {{{2z(z+10)(z-3)}}}
