Use the quadratic formula.

Answer 2

I know how to do that i just dont know what to do after i put the numbers in

Answer 3

\[x = \frac{ -b \pm \sqrt {b^2 - 4ac} }{ 2a }\]
a = 3 , b = 3 , c = 5

Answer 4

just plug them in and simplify.

Answer 5

I'll get you started.
\[x = \frac{ -3\pm \sqrt {3^2 - 4(3)(5)} }{ 2(3) }\]

Answer 6

-3 +- sqrt(3^2 -4 (3)(5)
--------------------
2(3)
?? is that right?

Answer 7

Yeah

Answer 8

ok, im not sure how to simplify tho

Answer 9

Simplifying.
We get.
\[x = \frac{ -3 \pm \sqrt{9-60} }{ 6 }\]
\[x = \frac{ -3 \pm \sqrt{-51} }{ 6 }\]
\[x = \frac{ -1 \pm \sqrt{-51} }{ 2 }\]
