Solve the equation by isolating the variable you're solving for on one side of the equation and get everything on the opposite side.

The x variable is being square and is being subtracted by 64.
Find the inverse of all of these operations.
First, get rid of the subtraction operation. The inverse of subtraction is addition.
Add 64 to both sides of the equation.

Now the variable x is only being squared. Reverse this operation by using the inverse of exponents.
Take the square root of both sides.

So, x is equal to 8.
