I took the expression under the radical and I completed the square, yielding: [itex]\int\frac{1}{\sqrt{5-(x+2)^2}}dx[/itex]

Then I figured that I could apply the arcsin formula, where [itex]a^2=5[/itex] and[itex]u^2=(x+2)^2[/itex]

But by solving for "a" and "u," I would be left with two roots, wouldn't I?
