Quadratic Formula
-b+or- the square root of b squared - 4ac over 2a
To find the discriminant
b squared - 4ac
When b squared - 4ac equals 0
one solution, one x-int, one real solution, vertex of parabola
When b squared - 4ac is greater than 0
2 solutions, 2 x-ints, 2 real solutions, 2 real zeros
When b squared - 4ac is less than 0
2 complex (imaginary solutions), no x-ints
Vertex Form
y-k=a(x-h) squared
If a is positive, which way does the parabola face?
If a is negative, which way does the parabola face?
To find the vertex of the standard form
h=-b over 2a
After finding h, how do you find k for the vertex?
plug in your answer for h into the original equation
