\[ \left \{ y \left ( x \right ) ={x}^{4}+{\it \_C1}\,x+{\it \_C1}+x+1 \right \} \] Mathematica raw input
DSolve[(1 + x)*y'[x] == x^3*(4 + 3*x) + y[x],y[x],x]
Mathematica raw output
{{y[x] -> 4 + x^4 + C[1] + x*(4 + C[1])}}
Maple raw input
dsolve((1+x)*diff(y(x),x) = x^3*(4+3*x)+y(x), y(x),'implicit')
Maple raw output
y(x) = x^4+_C1*x+_C1+x+1
