Question

Use complete sentences to describe the steps involved in solving x2 − 64 = 0 two different ways.

Answer 1

1. First, add 64 to bith sides, cancelling one out and taking it to the other side, then dividing by two, giving you x=32.

2. Subtract 2x and take it to the other sude of the equation. Then divide -2 by -64, giving you x=32, due to the negative cancelling (turning to a positive).
