Hello there!

First, let's take a look at our equation.

x^(2) - 15 = 34
We need to isolate x^2 to completely square root both sides properly, so let's do so.
Add 15 to both sides to isolate
x^(2).

We are now left with:

x^(2) = 49
Now, square root both sides.

√(x^2) = x

√(49) = 7

We are now left with the solution:
x = 7

I hope this helps!
