Question

How do you solve the equation `x^2=289`?

Answer 1

See the entire solution process below:

Explanation:

To solve this take the square root of each side of the equation which will solve for `x` while keeping the equation balanced. However, remember, the square root of a number results in both a negative and positive solution.

`sqrt(x^2) = +-sqrt(289)`

`x = +-sqrt(289) = +-17`
