I have a function which is a sum of many terms which look like this: (2*(B-b)^2 - 2*(A-a)*c*d^2)/(4*b^2*(1-c*2)*d^2) I think the function is actually equal to 0, but I have a hard time in trying to simplify it in Mathematica. Any ideas or commands I should try? Any suggestions in general about simplifying formulas will also be greatly appreciated! Thanks a lot!
