Integration of a function

Using the MATLAB intergral function you can integrate a function between a min and max value. integral(fun,min,max)
But I was wondering how you can show the intergated equation in MATLAB?
For example, If i intergrate I would get . How can a display that in MATLAB.
Thanks

Integral is a NUMERICAL tool for integration, uing adaptive numerical methods. It will return a NUMERICAL result, and only applies to definite integrals. Nothing more.
You need to use symbolic tools to perform an integration. That means you need to use syms.
syms x % creates x as a symbolic variable
int(x^2 + 2) % use int, NOT integral

syms x
f = 3*x-x^2 ;
F = int(f,x);
expand(F)
ans =
