`x^(3) + x^(2)y+ xy^(2) + y^(3) = 81`

Add : x^(3) - x^(2)y + 5xy^(2) + y^(3) , -x^(3) - 9xy^(2) + y^(3), 3x^(2)y + 9xy^(2)

x^(3) + xy^(2) - x^(2) y - y^(3) = "_______"

Find (dy)/(dx) if x^3 + x^2y + xy^2 + y^3 = 81

find dy/dx if x^3 + x^2 y + x y^2 + y^3 = 81

Find dy/dx in the following: x^3 +x^2y + xy^2 + y^3 = 81

Perform the division: (x ^(3) y ^(3) + x ^(2) y ^(3) - xy ^(4) + xy)div xy

The factors of x^(3)-x^(2)y-xy^(2)+y^(3) are (a (x+y)(x^(2)-xy+y^(2))(b)(x+y)(x^(2)+xy+y^(2))(c)(x+y)^(2)(x-y)(d)(x-y)^(2)(x+y)
