Homework Statement
Solve xy' + 2y = sqrt(1 + x^2)
Homework Equations
I got an integrating factor of [itex]x^2[/itex]
So [tex]y = 1/x^2 \int{x\sqrt{1 + x^2}}[/tex]
The Attempt at a Solution
and I get [tex]y =\frac{(1 + x^2)^{3/2}}{3x^2}[/tex] for C = 0
But this wrong when I substitute it in ... what'd I do wrong?
