i am trying to solve ((a+b)^2 -2*a*b -a^2)/b^2
using inline function I am getting output, but with normally(using solve and function) either I am getting an error or output as zero(where as I must get only 1).how should I program it?? further i need to create it on Xcel. how to do that??

To get just ans=1 you need the Symbolic Math Toolbox™
syms a b
simplify(((a+b)^2 -2*a*b -a^2)/b^2)
ans =
1

with the solution u have given is returning me this
ans =
- (2*a)/b - (a^2 - (a + b)^b)/b^2

What do you get if you try simple instead of simplify?

Notice the ^b in your output. It is an indication that very likely you have a typo in the equation you are requesting to be solved, or else the equation to be solved is not the one you showed to us. Another possibility is that you have given values to "a" or "b" before you reach this section of the code.
