x² = 64 is our given equation. Because we have only x² on the left side we can take roots of both sides. The square root of x² would be x. Then,

x = + 8 or - 8. We need the plus or minus because both 8² and (-8)² would both multiply to 64.


Thus the second choice (first as the left most) is the best answer.
