Very quick math question

[CommissarRezail]

I'm in dire need here. I want to know do both complete the sqaure and quadratic equation give the same answer for the same formula?

Or do they end up with two different answers

Because i'm getting two different answers no matter how many times i do them.

I hope the mods that lock this >.> very quickly.
