Well, I will follow through with the suggestion of the other solver.
I will multiply by x^m.y*n.
(x^my^(n+1)-x^(m+1)y^(n+2))dx + (x^(m+1)y^n+x*(m+2)y^(n+2)$dy = 0.
del M/del y = (n+1)x^m y^n-(n+2)x^(m+1)y^(n+1),
del N/del x= (m+1)x^my^n+(m+2)x^(m+1)y^(n+2).
I am wasting too much time on this. It does not seem to be working!
Maybe I have made some errors? I leave it to you. I’m off to bed.

Answer:
{x²+1} .{y²+1} = K
Step-by-step explanation:
(xy²+ x) dx + (yx²+y)dy = 0
(yx²+y )dy = -(xy²+ x) dx
re-arranging x,y to make it variable separable
x dx /(x²+1) = - y dy/(y²+1)
2 x dx /(x²+1) = - 2y dy/(y²+1)
integrating both sides
Ln{x²+1} =- Ln{y²+1) +C
Ln({x²+1} .{y²+1}) = C
{x²+1} .{y²+1} = K ( k is arbitrary Constant) is general solution
