## (c) ( y 2 + x y + 1 ) dx + ( x 2 + x y + 1 ) dy = 0. With M = y 2 + x y + 1 and N = x 2 + x y + 1, note that ( N x - M y) / ( x M - y N ) = ( x - y ) / ( x ( y 2 + x y + 1 ) - y ( x 2 + x y + 1 ) ) = ( x - y ) / ( x - y) = 1. Thus, μ = exp ( ∫ d(xy) ) = e xy is an integrating factor. The transformed equation is: Expert Answer 100% (49 ratings) Previous question Next question Often the objective is to simply get the dy on one side of the equation and the dx on the other: dy/dx = (2x-y+1) / (x-2y-1) dy/dx * dx = (2x-y+1) / (x-2y-1) * dx dy = (2x-y+1)dx / (x-2y-1) Now resolve the fractions so that there are none.

## It’s a Bernoulli type equation.We assume y(x) = v(x)^(1/4) and obtain the equation : v’(x) + (2/x)v(x) = 4x.The integrating factor is exp(integral(2/x)) = x^2 so

Thus it is a solution. Question: Dy/dx-y=e^x Y^2. This problem has been solved! See the answer. dy/dx-y=e^x y^2.
