How do I figure out the root of x^2 - 5x - 1 = 0

OpenStudy (luigi0210):

Use the quadratic formula

OpenStudy (austinl):

\(x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\)

OpenStudy (anonymous):

Plug the values into the quadratic formula :)

OpenStudy (luigi0210):

Yea, the formula Austin has provided above, do you know what each variable stands for?

OpenStudy (anonymous):

Okay so a being x^2, b being 5x and 1 being c.?

OpenStudy (luigi0210):

Sorry about that.. it shut down on me. -_- but remember your negatives.

OpenStudy (anonymous):

Its fine, it shut me down also haha. but I got 5 + ((sq) (29)) / 2 turns out to be correct.!

OpenStudy (luigi0210):

Hooray!

OpenStudy (anonymous):
