Integrate the function $\sqrt{x^2+4x-5}$

Question

$\begin{array}{1 1} \frac{(x+2) (\sqrt{x^2+4x-5})}{2}-\frac{9}{2} \log \mid (x+2)+\sqrt{x^2+4x-5}\mid+c \\ \frac{(x+2) (\sqrt{x^2+4x-5})}{2}+\frac{9}{2} \log \mid (x+2)+\sqrt{x^2+4x-5}\mid+c \\ \frac{(x+2) (\sqrt{x^2+4x-5})}{2}-\frac{9}{2} \log \mid \sqrt{x^2+4x-5}\mid+c \\ \frac{(x+2) (\sqrt{x^2+4x-5})}{2}+\frac{9}{2} \log \mid (x+\sqrt{x^2+4x-5}\mid+c\end{array}$
