Cant go wrong always using the quadratic formula

danjs · Answer

i would try to factor it first before that though...

anonymous · Answer

True.. I'll try that. @DanJS

danjs · Answer

9  1               2   1
3  3

i think you can make that +3 in the middle from those

danjs · Answer

3*2 - 3*1

danjs · Answer

Or just use the quadratic formula,, reason: always works.. :)

@DanJS

danjs · Answer

hmm...
real fast by factoring first

$$9x^2+3x-2 = (3x - 1)*(3x+2) = 0$$

danjs · Answer

so either of those quantities in (  ) can be zero to be true

3x - 1 = 0
or
3x + 2 = 0

danjs · Answer

so you have it right, just decimal form

danjs · Answer

x = + 1/3
or x = - 2/3

i would leave it like that

anonymous · Answer

Alright, I got it now. Thanks for the help!
