DSolve[-12*y[x] - 8*x*y'[x] + (a^2 - x^2)*y''[x] == 0,y[x],x]
Mathematica raw output
{{y[x] -> (3*C[1] + ((a^2 + 3*x^2)*C[2])/(a - x)^3)/(3*(a + x)^3)}}
Maple raw input
dsolve((a^2-x^2)*diff(diff(y(x),x),x)-8*x*diff(y(x),x)-12*y(x) = 0, y(x))
Maple raw output
[y(x) = _C1/(a-x)^3/(a+x)^3*(a^2+3*x^2)+_C2*x*(3*a^2+x^2)/(a-x)^3/(a+x)^3]
