Solve by reduction of order:
yy''=3y'^2
The answer the book has is y=(c1*x+c2)^(1/2)
I can't figure out how to put it in standard form to get the above answer.

No, I'm not sure how to go about doing this problem :/ I know that for a homogeneous 2nd order ODE, the solution is y=c1y1+c2y2 but since the above equation cannot be put in standard form I can't see how to solve it. I should add that the problem wants me to use reduction of order, where I first pick a y1 solution by inspection, then get y2 using: \[y_2=y_1u=y_1\int\limits_{}^{}U\;dx\] where \[U=\frac{ 1 }{ y^2 }e^{\int\limits_{}^{}p\;dx}\] I can do it for a regular problem but I'm lost on this one...

so first we need to find \(y_1\), a solution to the equation, i'm not sure how to do this
