I have following problem:

let's assume this nonlinear differential equation
$$y''(x)+ay(x)+by'(x)^2=0$$
for unknown function $y(x)$ of one variable $x$ and $a,b \in \mathbb{R}$ are real parameters. Is there any method to find general solution? I can only find solution for $b=0$ as it is then linear ode.

P.S. Does this equation have a special name?
