square both sides.

Square both sides.

Since we are dealing with square roots, it may be a good idea to check our answers to see that we aren't getting extraneous answers.

When we plug in 2 we get sqrt(36) + sqrt(0) = 6
When we plug in 58/11 we get sqrt(9216/121) + sqrt(900/121) = 11.45.. which is not 6.
That means the only answer that works is x=2.
