1.`y(x^4y^4+x^2y^2+xy)dx+x(x^4y^4-x^2y^2+xy)dy=0`

y(xy+1)dx+x(1+xy+x^(2)y^(2))dy=0

The solution of the differential equation y(xy+2x^(2)y^(2))dx+x(xy-x^(2)y^(2))dy=0, is given by

y^(2)dx+(x^(2)+xy+y^(2))dy=0

(x^(3)+xy^(4))dx+2y^(3)dy=0

If x^2+y^2=7 and xy=2 then x^4-2x^2y^2+y^4=

(dy)/(dx)=(x^2y+y)/(xy^2+x)
