How do you factor completely x^3 y^3 z^3 3xyz?For xaxis to be the tangent of the curve x 3 y 3 = 3 x y, first you need to check if the curve intersects or touches with xaxis Since on xaxis y = 0 which should also satisfy x 3 y 3 = 3 x y Substituting y = 0, we obtain x 3 0 = 0 Which is satisfied for x = 0 Hence the curve touches or intersects with xaxis at (0, 0)Differentiate with respect to x 3x^2 3y^2dy/dx=3(xdy/dx y) 3x^23y^2dy/dx =3xdy/dx3y 3y^2dy/dx3xdy/dx=3y3x^2 dy/dx(3y^2–3x)=3y3x^2 dy/dx=(3y3x^2)/(3y^2–3x
