Question 196861
{{{((x^3+y^3)/(2x^3+2x^2y))/((3x^3-3x^2y+3xy^2)/(6x^2-6y^2))}}}
= {{{((x^3+y^3)*(6x^2-6y^2))/((2x^3+2x^2y)*(3x^3-3x^2y+3xy^2))}}}
= {{{((x^3+y^3)*(x^2-y^2))/((x^3+x^2y)*(x^3-x^2y+xy^2))}}}
= {{{((x+y)*(x^2+xy+y^2)*(x-y)*(x+y))/(x^2*(x+y)*(x^3-x^2y+xy^2))}}}
= {{{((x+y)*(x-y)*(x^2+xy+y^2))/(x^3*(x^2-xy+y^2))}}}
