Linear Differential Equation - Initial Value Problem

  • #1
Hello, I'm struggling with a simple problem here.

It asks me to solve the following initial value problem:

So far I've calculated the integration factor μ(x) = ex-x2 and I multiplied both sides of the equation by it and got this:

The problem I'm having is that the equation I got is different than the equation in the first line of the solution:

I don't understand how the ex-x2⋅(1 - 2x)⋅y disappeared


EDIT: Actually, nevermind. My brain was too lazy to realize that the left part of the equation is equal to the derivative of ex-x2⋅y so I could just simplify it
