Solve the following equation

, ,

Did the following to put in form y'+P(x)y=Q(x)

Than P(x) and the integrating factor are

Multiply by integrating factor and integrate RHS

So give that when x=1 y = 0, solve for C

and so initial value problem I worked out to be

However the answer to the problem is where they worked C= -1

Can someone tell me here what I have done wrong? Or is the answer in the text wrong?
