rewrite it as
\[6x^2 + 6x + 1 = 0\]
now just use the general quadratic formula
\[x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\]
and from your question a = 6, b = 5 and c = 1
hope it helps...
the solutions are real but irrational

im going to try it right now
OpenStudy (anonymous):
is the answer x= -1/2, -1/3?
OpenStudy (triciaal):
and from your question a = 6, b = 5 and c = 1
right formula
b = 6
OpenStudy (triciaal):
a = 6, b = 6 c = -1

aaaahhhhhhhhhhh how did you get that
OpenStudy (triciaal):
@campbell_st has the correct formula but the values for a, b and c he made an error.
the equation is rewritten in the form ax^2 + bx + c =0 to pick up the values
6x^2+6x=1 6x^2 + 6x -1 = 0
OpenStudy (triciaal):
when I did it the values for x were -3 + rt 3; -3 -rt 3

thank you
OpenStudy (triciaal):
you need to redo with c = -1
