dsolve(y(x)+(1+2*x)*diff(y(x),x) = (1+2*x)^(3/2),y(x), singsol=all)
 
\[ y = \frac {x^{2}+c_1 +x}{\sqrt {2 x +1}} \]

Solution by Mathematica

DSolve[y[x]+(1+2*x)*D[y[x],x] == (1+2*x)^(3/2),y[x],x,IncludeSingularSolutions -> True]
 
\[ y(x)\to \frac {\frac {x \sqrt {-(2 x+1)^2} (x+1)}{2 x+1}+c_1}{\sqrt {-2 x-1}} \]
