Detail solution

    SqrtQuadraticRule(a=1, b=0, c=1, context=sqrt(x**2 + 1), symbol=x)

  1. Add the constant of integration:

    xx2+12+asinh⁡(x)2+constant\frac{x \sqrt{x^{2} + 1}}{2} + \frac{\operatorname{asinh}{\left(x \right)}}{2}+ \mathrm{constant}

The answer is:

xx2+12+asinh⁡(x)2+constant\frac{x \sqrt{x^{2} + 1}}{2} + \frac{\operatorname{asinh}{\left(x \right)}}{2}+ \mathrm{constant}
