Could someone help me out, please? =) (Algebra 2)

Eloise started to solve a radical equation in this way: Both solutions are extraneous because they don't satisfy the original equation. What error did Eloise make? She added 2x after squaring both sides. She subtracted 1 before squaring both sides. She factored x2 + 10x + 16 incorrectly. She did not check for extraneous solutions.
