You can use the quadratic formula, \[ x = \frac{ -b \pm \sqrt{b^2-4ac} }{ 2a }\]

OpenStudy (anonymous):

The standard form of a quadratic equation looks like ax^2+bx+c = 0 a =? b =? c =?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

\[x^2-3x-1=0\] What are the values of a, b, and c here?

OpenStudy (anonymous):

how i get do them? how i find a b and c?

OpenStudy (anonymous):

Well you have a quadratic equation as I mentioned above, and the standard form looks like \[ax^2+bx+c=0\] Now looking at your problem, what would your a, b, and c be?

OpenStudy (anonymous):

i don't know how i suppose to do that because where i start i don't know :(
