Best ResponseYou've already chosen the best response.1Did you add 15 to both sides?

Best ResponseYou've already chosen the best response.0\[\sqrt{2x+13} = x + 15\]

Best ResponseYou've already chosen the best response.1What do you get if you square the left side?

Best ResponseYou've already chosen the best response.1Sorry. I meant + 13 not =

Best ResponseYou've already chosen the best response.0\[\large{\sqrt{2x+13}15=x}\]\[\large{\sqrt{2x+13}=x+15}\]Now squaring both sides we get\[\large{2x+13=x^2+225+30x}\]

Best ResponseYou've already chosen the best response.1You must not square each side. So now it will look like this: \[(\sqrt{2x+13})^2=(x+15)^2\]

Best ResponseYou've already chosen the best response.0Thanks for leaving I guess... @Mertsj @TheViper are you leaving too or saying goodbye to the other guy?

Best 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 :)

Best ResponseYou've already chosen the best response.0You two were both telling me different things. How do I know that yours it right?

Best ResponseYou've already chosen the best response.1It won't factor. You'll have to use the quadratic formula.

Best ResponseYou've already chosen the best response.0I tried factoring and it didn't work. So I plug x^2 + 28x + 212 into the quadratic formula?

Best ResponseYou've already chosen the best response.0I think it should be \(14+2i\) \(\&\) \(142i\)
