I = ∫x2+elogx+(e/2)dx
Let I1 = ∫xdx = x3/3 + C
     I2 = ∫elogx dx
 put, logx = t  ,after solving we find_
                                     I2= e2logx +C1
I=∫(e/2)dx
put ,  (e/2)x = z
  or, log(e/2)x = logz
x.log(e/2) = logz
differentiate both side,
log(e/2)dx = (1/z)dz
now, I3 = ∫{z/log(e/2).z} dz 
I= 1/log(e/2)∫dz
I3 = z/log(e/2) + C2
I= (1/log(e/2)(e/2)+C2
I = I1 + I2 + I3
I = x3/3 + e2logx+(e/2)x/log(e/2) +K
