Step-by-step explanation:
To complete the square, we first have to get our equation into
form.
First we add 16x to both sides:

And now we subtract 62 from both sides.

We now have to add
to both sides of the equation. b is 16, so this value becomes
.

We can now write the left side of the equation as a perfect square. We know that x+8 will be the solution because
and
.

We can now take the square root of both sides.

We can now isolate x on one side by subtracting 8 from both sides.

So our solutions are
