|3n-6|= 12

3n-6=12
3n= 18
n= 6

or

3n+6=12
3n= 6
n= 2

Which is it? Or is it both?

Hi, I'm completely lost when it comes to algebra. Please, explain step by step how you solved the equation. And any suggestions of websites that help you understand algebra clearly. Please don't suggest quickmath.com, it just solves the answers but it doesn't help at all.
Thanks,

Look at the graph above and comment on the sign of D or the discriminant. Form the quadratic equation based on the information provided and find its solution.

The equation is

y = ax^2 + bx + c

One approach: Put each (x, y) pair that you have in to get three equations. Then solve them to find a, b, and c.

A different approach: If (s,0) and (t,0) are where the parabola crosses the x-axis, then the equation is y = a(x - s)(x - t)
To find a, put that vertex you are given in to find the equation.
