So, here's my code:
syms w k c l Vi Vr p wr wi
l = (Vr-Vi)/Vi;
p = w/wr;
fw = ((k*l*Vi)/c)*(((1+p*l)*Vi)/c)^(k-1)*exp(-((1+p*l)*Vi)/c)^k ;
f1 = wi-w;
f2 = w-wi;
fr = (f1*fw);
fp = (f2*fw);
CCr = int(fr,w);
CCp = int(fp,w);
w is the only real variable. The others ( k,c,l,Vi,Vr,p,wr,wi) are constants, but i need the answer without using the values of these.
When i try to use the ''int'' it doesn't integrate and returns int(fw,w).
Thank you :)

Many functions do not have analytic (symbolic) integrals. This also applies to differential equations, so in those situations, only numeric solutions are possible.
