Question 190274
{{{15+3y-5x^2-x^2y}}} Start with the given expression



{{{(15+3y)+(-5x^2-x^2y)}}} Group like terms



{{{3(5+y)-x^2(5+y)}}} Factor out the GCF {{{3}}} out of the first group. Factor out the GCF {{{-x^2}}} out of the second group



{{{(3-x^2)(5+y)}}} Since we have the common term {{{5+y}}}, we can combine like terms



So {{{15+3y-5x^2-x^2y}}} factors to {{{(3-x^2)(5+y)}}}
