Question 25638
Simplify the expression: (You don't "solve" expressions, you simplify them)
{{{(x^3-y^3)/((x^2+xy+y^2))}}} The numerator is the difference of two cubes and can be factored.
{{{((x-y)(x^2+xy+y^2))/((x^2+xy+y^2))}}} Cancel the like-terms{{{(x^2+xy+y^2)}}} in the top and bottom.
{{{x-y}}} This is the answer!
