Is there a software that simplify mathematical expressions?

When I work with circuits that contains some capacitors, inductors and resistors and the supply is AC, I get long mathematical expressions and I have to do many calculations and many steps.
I would like to use an online website or a free software that is able to simplify these expressions. I need the software to support complex numbers or square root of (-1).

To clarify what I need, Here is a quick example:
I need the software to expand this expression (R1 - i * Xc) * (R2 + R3) to this expression
R1*R2 + R1*R3 - i*Xc*R2 - i*Xc*R3

Also, It is better if the software supports ratios.

I would be grateful if you give me a link or a software,
Thank you very much,

WolframAlpha.com

Will do it. You cannot have variables with two characters so change R1, R2 and R3 to a, b and c. Xc to x.

Just plug formula into search bar and it will solve for you.

These things can be done easily in Mathematica or Maple.
