I cant solve this problem. help please thanks
oh. the last term has the denominator of xcube - 2xsquared y + 2x ysquared - ycube.
hope you guys can answer.
Hello reiwardYou'll find the following expressions useful:
$\displaystyle x^3 -2x^2y+2xy^2 - y^3 = (x-y)(x^2-xy+y^2)$
This will enable you to find the LCD of the two fractions in the last bracket; and
$\displaystyle x^3 + y^3 = (x+y)(x^2-xy+y^2)$
This will allow you to cancel a common factor once you've turned the 'divided by' fraction 'upside-down'.
