\[ \left \{ y \left ( x \right ) =x \left ( \sqrt {-1+x}\sqrt {1+x}{\it \_C1}+a \right ) \right \} \] Mathematica raw input
DSolve[x*(1 - x^2)*y'[x] == a*x^3 + (1 - 2*x^2)*y[x],y[x],x]
Mathematica raw output
{{y[x] -> x*(a + Sqrt[1 - x^2]*C[1])}}
Maple raw input
dsolve(x*(-x^2+1)*diff(y(x),x) = a*x^3+(-2*x^2+1)*y(x), y(x),'implicit')
Maple raw output
y(x) = x*((-1+x)^(1/2)*(1+x)^(1/2)*_C1+a)
