9x^-3x-2 please help solve this

OpenStudy (john_es):

Do you mean \[9x^2-3x-2=0\] ?

OpenStudy (anonymous):

yes sorry

OpenStudy (john_es):

You need to apply the second grade equation. The general formula for \[ax^2+bx+c=0\]is, \[x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\]with a=9, b=-3 and c=-2. Could you solve the problem with this information?

OpenStudy (john_es):

You're welcome.
