Question 118849

{{{xy+10x-4y-40}}} Start with the given expression


{{{(xy+10x)+(-4y-40)}}} Group like terms



{{{x(y+10)-4(y+10)}}} Factor out the GCF {{{x}}} out of the first group. Factor out the GCF {{{-4}}} out of the second group



{{{(x-4)(y+10)}}} Since we have the common term {{{y+10}}}, we can combine like terms


So {{{xy+10x-4y-40}}} factors to {{{(x-4)(y+10)}}}
