    Mathematica Help with Mathematica Issue: Solving Nonlinear Second Order ODE

    i am tryin to solve this (sorry i am not good writin it in latex): d*y''(x)+a*y(x)*y''(x)+a*(y'(x))^2-b*x-c*y(x)-f*(y(x))^2-g=0 as i said before, d,a,c,b,g are arbitrary constants... Am i writing this wrong, or there is not analytical solutions?
