Hand solution
\(xy^{\prime }+axy^{2}+2y+bx=0\)This is Riccati non-linear first order. Converting it to standard form\begin {align} xy^{\prime }-y\left (2y\ln x-1\right ) & =0\nonumber \\ xy^{\prime } & =y\left (2y\ln x-1\right ) \nonumber \\ y^{\prime } & =-\frac {1}{x}y+y^{2}\frac {2}{x}\ln x\tag {1}\\ y^{\prime } & =f_{0}+f_{1}y+f_{2}y^{2}\nonumber \end {align}
This is Bernoulli non-linear first order ODE since \(f_{0}=0\). Dividing by \(y^{2}\) gives\[ \frac {y^{\prime }}{y^{2}}=-\frac {1}{x}\frac {1}{y}+\frac {2}{x}\ln x \] Putting \(u=\frac {1}{y}\), hence \(u^{\prime }=-\frac {y^{\prime }}{y^{2}}\), and the above becomes\begin {align*} -u^{\prime } & =-\frac {1}{x}u+2\frac {\ln x}{x}\\ -u^{\prime }+\frac {1}{x}u & =2\frac {\ln x}{x}\\ u^{\prime }-\frac {1}{x}u & =-2\frac {\ln x}{x} \end {align*}
Integrating factor is \(\mu =e^{\int -\frac {1}{x}dx}=e^{-\ln x}=\frac {1}{x}\), hence\begin {align*} d\left (\mu u\right ) & =-2\mu \frac {\ln x}{x}\\ d\left (\frac {1}{x}u\right ) & =-2\frac {\ln x}{x^{2}} \end {align*}
Integrating\begin {align*} \frac {1}{x}u & =-2\int \frac {1}{x^{2}}\ln xdx+C\\ & =-2\left (-\frac {\ln x}{x}-\frac {1}{x}\right ) +C \end {align*}
Therefore\begin {align*} u & =-2x\left (-\frac {\ln x}{x}-\frac {1}{x}\right ) +Cx\\ & =2\left (\ln x+1\right ) +Cx \end {align*}
Since \(u=\frac {1}{y}\) then\[ y=\frac {1}{2\left (\ln x+1\right ) +Cx}\] Verification
