lets say that I have the equation 2*x^2 + 3*y^2. I need to do 2 things. I need to extract the 2*x^2, and then I need to extract the coefficient 2. Anyone know how to do that?

See indets and coeff
Please note that both of those are part of the MuPAD Standard Library, available for calling within MuPAD itself, but there is no MATLAB interface to them. You will need to use feval(symengine,...) or evalin(symengine,...) to access them.
