i bet you can do this divide by 3 first
then, because the middle term is going to have an even coefficient (namely 4) solve by completing the square
divide 12 by three?
i can walk you through it if you like or else you can try first
I'll come up with an answer first :)

divide everything on both sides of the equal sign by 3, everything
The expression is the same as: \[3x^2+12x−3=0\] Now notice they all can divide by 3, we get \[x^2+4x−1=0\] Now use the technique I taught you in your last 'finding zero' question
Nevermind, use the quadratic formula
-2 _+_ sq root 3
nop :(

\[x^2+4x=1\]\[(x+2)^2=1+4=5\] \[x+2=\pm\sqrt{5}\]
