Question 57384
{{{((x^2+2xy+y^2)/(x+y))*((x^2-y^2)/(x-y))}}} First factor everything you can.
{{{((x+y)(x+y)/(x+y))*((x+y)(x-y)/(x-y))}}}  Cancel all numerators and denominators that match each other.
{{{(cross((x+y))(x+y)/cross((x+y)))*((x+y)*cross((x-y))/cross((x-y)))}}}
{{{(x+y)*(x+y)}}} some teachers like this: {{{(x+y)^2}}}
Others want you to FOIL it.
{{{x(x)+x(y)+y(x)+y(y)}}}
{{{x^2+xy+xy+y^2}}}
{{{x^2+2xy+y^2}}}
