Solve \begin {gather*} \boxed {\left (\mathit {a2} x +\mathit {c2} \right ) \left (y^{\prime }\right )^{2}+\left (\mathit {a1} x +\mathit {b1} y+\mathit {c1} \right ) y^{\prime }+\mathit {a0} x +\mathit {b0} y+\mathit {c0}=0} \end {gather*}

Solution by Maple

Time used: 0.375 (sec). Leaf size: 9885

dsolve((a2*x+c2)*diff(y(x),x)^2+(a1*x+b1*y(x)+c1)*diff(y(x),x)+a0*x+b0*y(x)+c0 = 0,y(x), singsol=all)
