is it x=-b(+/- ..... all of that?

mathmale · Answer

Yes.  You do need to know that formula (all of that).

Could you please look up "quadratic formula"?  I'd like for you to have the experience of finding info quickly on your own when you need to.  Have you a textbook handy?  Or are you good at Internet searches?  Could you please type out the quadratic formula?

mathmale · Answer

the quadratic formula looks like the following (incomplete):

$$x=\frac{ -b  \pm \sqrt{?}}{ 2a }$$    Please fill in the missing info under the radical sign.
