MATLAB: Cant simplify an algebraic equation

MATLABsimplify

Hello,
I can't simplify this equation:
g(x) = (A*(x + 1)^3 + C*(x + 1)^3 + B*(x - 1)*(x + 1)^2)/((x - 1)*(x + 1)^3)
I tried to use
simplify(g(x))
But It doesn't work.

Best Answer

It seems to slimplify nicely for me:
syms A B C x
g(x) = (A*(x + 1)^3 + C*(x + 1)^3 + B*(x - 1)*(x + 1)^2)/((x - 1)*(x + 1)^3);
g = simplify(g, 'Steps', 20)
g(x) =
A/(x - 1) + B/(x + 1) + C/(x - 1)
Do you want something different?
