it will convert into the integral of (x/x +2sqrtx/x+1/x)
then simplize it into integral of (1+2/sqrtx + 1/x)
so integrate: int(1)=x
int(2/sqrtx)=2sqrtx
int(1/x)=ln x
result : x+2sqrtx + lnx

\[\int\limits 1{}^{?}\] = 1
\[\int\limits 2/\sqrt{x} {?}^{?}\]=\[2\sqrt{x}\]
\[\int\limits1/x{?}^{?}\]=\[\ln x\]
