Question

Stephanie is a student teaching at her local high school. She has to help her instructor write a test.

Answer 1

There are two questions I just can't figure out, can you please help me?

1. Stephanie is student teaching at her local high school. She has to help her instructor write a test. She has to write a radical equation where the solutions are extraneous. She also has to write a radical equation where the solutions are non-extraneous. Help Stephanie write one radical equation where the solution is extraneous and another equation where the solution is non-extraneous. Using complete sentence, explain each step.

::Now I already know what extraneous means and what isn't extraneous and I can take care of putting it into sentences. I just need those equations because I don't think I'm doing it right.
