The solutions of equations that need numerical approximations to be solved are now computed base on the undeveloped equation (instead of fully the expended one used to identify polynomials) This allow (x-10)^7=0 to yield x=10 as result (9.95 before) Change-Id: Ia8acbe57a9cfebf0b5016e9c896d21c8ddac7a64
