HELP simple question

Answer 1

Step one.

Explanation:

She needed to move all terms to the left side of the equation and simplify, she should have subtracted 245 from both sides and ended up with an equation that looked like this:

5(x+7)^2-245=0

Note: ^2 is a superscript.

Answer 2

I think it’s step 2 where she distributed the exponents incorrectly but she got it right so since no explanation is really needed then I guess it’s step 2.

step 1 where she divided 5 on both sides. Step 3 is also correct since the answer is 0. so step 2 had the mistake.
