Front

What does the discriminant tell us?

Back

The discriminant indicates how many solutions to expect for a quadratic equation.

Front

Factor by grouping: x^3 - 4x^2 - 4x + 16

Back

(x - 4)(x - 2)(x + 2)

Front

What piece of information does h identify in the equation y=a(x-h)^2+k?

Back

h identifies the axis of symmetry of the parabola.

Front

What is the name of the expression b^2-4ac?

Back

Discriminant

Front

Use the quadratic formula to find the solutions for y = -x^2 - 5x + 12.

Back

x = -2.5, 18.25

Front

What is the standard form of a quadratic equation?

Back

The standard form is y = ax^2 + bx + c.

Front

What does the vertex of a parabola represent?

Back

The vertex represents the maximum or minimum point of the parabola.

Front

How do you find the axis of symmetry for a quadratic equation?

Back

The axis of symmetry can be found using the formula x = -b/(2a).

Front

What is the quadratic formula?

Back

The quadratic formula is x = (-b ± √(b^2 - 4ac)) / (2a).

Front

What does the 'a' value in the quadratic equation y = ax^2 + bx + c determine?

Back

The 'a' value determines the direction of the parabola (upward if a > 0, downward if a < 0).
