Add 15 to both sides and then square both sides.

I'm still kind of confused

Did you add 15 to both sides?

Yeah, I did.

What did you get?

\[\sqrt{2x+13} = x + 15\]

What do you get if you square the left side?

\[(\sqrt{2x=13})^2= ?\]

Sorry. I meant + 13 not =

You must not square each side. So now it will look like this:
\[(\sqrt{2x+13})^2=(x+15)^2\]

ok. Too many cooks. Good bye

bye :)

no

Okay haha

You two were both telling me different things. How do I know that yours it right?

We are telling same but concentrate on mine because I m here to help you :)

It won't factor. You'll have to use the quadratic formula.

I tried factoring and it didn't work. So I plug x^2 + 28x + 212 into the quadratic formula?

yes

yup :)

I think it should be \(-14+2i\) \(\&\) \(-14-2i\)

Check ur calculation again :)
