Quadratic equation (in our case ) has the following solutons:



For these solutions to exist, the discriminant should not be a negative number.

First, we need to compute the discriminant : .

Discriminant d=24 is greater than zero. That means that there are two solutions: .




Quadratic expression can be factored:

Again, the answer is: 1.81649658092773, 0.183503419072274. Here's your graph:

can you help me graph this parabola?
y= 3x^2 - 6x + 1
vertex is one, minus two
opens up
pick some whole numbers for x and calculate y
choose some x above and below 1 so that you gets both sides of the parabola.
