Explanation Definition used: Let the functions M , N , M y and N x , where subscripts denote the partial derivatives, be continuous in the rectangular region R : α < x < β , γ < y < δ . Then the equation M ( x , y ) + N ( x , y ) y ′ = 0 is an exact differential equation if and only if M y ( x , y ) = N x ( x , y ) at each point R. That is, there exists a function ψ satisfying ψ x ( x , y ) = M ( x , y ) , ψ y ( x , y ) = N ( x , y ) . Calculation: The given differential equation is d y d x = − 2 x y + y 2 + 1 x 2 + 2 x y . Rewrite the given differential equation as, d y d x = − 2 x y + y 2 + 1 x 2 + 2 x y ( x 2 + 2 x y ) d y = − ( 2 x y + y 2 + 1 ) d x ( 2 x y + y 2 + 1 ) d x + ( x 2 + 2 x y ) d y = 0 Note that, M = 2 x y + y 2 + 1 and N = x 2 + 2 x y . Differentiate M with respect to y and N with respect to x as, M y = 2 x + 2 y and N x = 2 x + 2 y Since the equation is exact, ψ x ( x , y ) = M ( x , y ) and ψ y ( x , y ) = N ( x , y )
