Your equation is already in the right format:
ax² + bx + c = 0

Your specific values are:
a = 3
b = -2
c = -2

Now plug that into the quadratic formula:

…… -b ± sqrt( b² – 4ac)
x = ————————–
……………… 2a

…… -(-2) ± sqrt( (-2)² – 4(3)(-2) )
x = ————————————–
……………… 2(3)

…… 2 ± sqrt( 4 – (-24) )
x = ————————–
……………… 6

…… 2 ± sqrt( 28 )
x = ——————
…………… 6

…… 2 ± sqrt( 4 * 7 )
x = ———————
…………… 6

…… 2 ± 2 sqrt( 7 )
x = ——————–
…………… 6

…… 1 ± sqrt( 7 )
x = —————–
…………… 3

So your answers are:
x = (1+?7) / 3 ? 1.21525
x = (1-?7) / 3 ? -0.54858

I’m relaxing here . . . why would I want to solve an equation as that ?

Another thought . . . questions as this posted during the school year often draw my mind to wonder if the person asking the question is a student trying to cheat and have another think and do their homework for them.

Additional note . . . I just looked at you past questions and they are about you asking the answer to some math equation. Trying to get others to do your homework?

3x^2 – 2x -2 = o
a x^2 -b x – c = o
x = 2 + or – (square root of 4 +24 ) / 6

x = (2 +/ – 5.3) / 6
x = 7.3/6 or -3.3/6

x = 1 and 13/6 or -11/20
