\begin {align} y^{\prime }+ay^{2}-bx^{2v}-cx^{v-1} & =0\nonumber \\ y^{\prime } & =bx^{v}+cx^{v-1}-ay^{2}\tag {1}\\ & =P\left ( x\right ) +Q\left ( x\right ) y+R\left ( x\right ) y^{2}\nonumber \end {align}
This is Riccati first order non-linear ODE with \(P\left ( x\right ) =bx^{v}+cx^{v-1},Q\left ( x\right ) =0,R\left ( x\right ) =-a\).
Need to do this later.
