See attached for some ideas. You may as well use the static symbolics but I usually don't as you have less control over the outcome and loose the dynamic.

Mathcads solution are ever so often quite complicated as the symbolics alway work in complex domain and have to consider all possible cases. Additional assumptions (if appropriate) can help. Somiting like "assume, x=real", or "assume, x>0, x>y". Unfortunately Mathcad quite often ignores the assume modifier.
