so you dont know it how ?
no
\[3x^{2}-7x-2=0\] Use the formula that jhonyy9 gave to calculate the Discriminant \[D=b^{2}-4ac\] now use the quadratic formula which is \[\frac{ -b \pm \sqrt{D} }{ 2a }\] where a=3 b=-7 and c=-2
uhm ?
we use these formula's to solve the quadratic equations - \[ax^{2}+bx+c=0\]
I have no idea how to do it
\[x=\frac{-b \pm \sqrt{D} }{ 2a }\]
just put the values. first to calculate D and then in the above formula.

is the answer \[x=\frac{ 7\pm \sqrt{73} }{ 6 }\]
yes :-) ..!!
