    \[3x^2+(-4)x+3=0 \\ \text{ compare this to } \\ ax^2+bx+c=0\] what does a,b,c have to equal ?

    \[a=3,b=-4,c=3 \\ x=\frac{-b \pm \sqrt{b^2-4ac}}{2a} \\ x=\frac{-(-4) \pm \sqrt{(-4)^2-4(3)(3)}}{2(3)}\] is correct so far

    \[x=\frac{4 \pm \sqrt{16-36}}{6} \\ x=\frac{4 \pm \sqrt{-20}}{6}\] that is also correct so far
