I'm a beginner with Matlab, and I don't know why MATLAB don't give me the answer for this integral
int((6719222573537927*exp((5*x)/2 - (15*u)/2)*(u + x)^(3/2)*(u - x)^19)/576460752303423488, u, abs(x), Inf).
Why? How can we get the result integration? Anyone could help me, please?

The expression is simply too complicated for MATLAB to integrate symbolically. There are other software vendors and tools that are more complete. Two of the leading commercial alternatives are Maple (Maplesoft) and Mathematica (Wolfram Research)
