Add 15 to both sides and then square both sides.

I'm still kind of confused

Did you add 15 to both sides?

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

What do you get if you square the left side?

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

Sorry. I meant + 13 not =

\[\large{\sqrt{2x+13}15=x}\]\[\large{\sqrt{2x+13}=x+15}\]Now squaring both sides we get\[\large{2x+13=x^2+225+30x}\]

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

Thanks for leaving I guess... @Mertsj @TheViper are you leaving too or saying goodbye to the other guy?

TheViperBest ResponseYou've already chosen the best response.0
\[\large{2x+13=x^2+225+30x}\]\[\large{\implies x^2+30x2x+22513=0}\]\[\large{\implies x^2+28x+212=0}\]Now solve it by factoring :)

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?

I think it should be \(14+2i\) \(\&\) \(142i\)
