Question 61586
{{{(x^5 + y^5) / (x + y)}}}
Do this by long division. You need to be pretty good at it to do
this problem. Get practice if you need it.
The answer is {{{x^4 - x^3y + x^2y^2 - xy^3 + y^2}}}
If you do the multiplication
{{{(x + y)(x^4 - x^3y + x^2y^2 - xy^3 + y^2)}}}, you'll get {{{x^5 + y^5}}}
