dsolve([diff(y(x),x)=2*x-1+2*x*y(x)-y(x),y(0) = 2],y(x), singsol=all)
 
\[ y = -1+3 \,{\mathrm e}^{\left (x -1\right ) x} \]

Solution by Mathematica

Time used: 0.056 (sec). Leaf size: 16

DSolve[{D[y[x],x]==2*x-1+2*x*y[x]-y[x],{y[0]==2}},y[x],x,IncludeSingularSolutions -> True]
 
\[ y(x)\to 3 e^{(x-1) x}-1 \]
