Well, you don't have it quite right!
If your equation is: , then a = 3, b = -6, and c = 2
Now if you apply the quadratic formula :
Simplifying this, you get:

Standard Form of a quadratic equation is
a=3, b=-6, c=2 (You had left the - off of the b.)
The Quadratic Formula is:
Plug your numbers into the formula:
We factor 12 into 4*3 because 4 is a perfect square. The square root of 4 is 2, but we can't take the square root of three.
I can't fix this glitch...+/-is supposed to be in front of the 2.
The 2'2 cancel because 2/2=1.
Happy Calculating!!!
