Factoring and Quadratics Vocabulary

A curve that is created when you graph a quadratic

• V

• vertical

• parabola

• axis of symmetry

The Area Model is used to change Factored Form into ________ .

• Standard Form

• Slope Intercept Form

• Quadratic Form

• Exponential Form

An example of Factored Form is:

• x² - x - 20

• (x - 5)(x + 4)

Factored Form, like 0 = (x - 5)(x + 4), can be solved using the Zero Product Property.

• True

• False

Which answer choice correctly shows the quadratic equation above in factored form?

• (x + 7)(x - 2) = 0

• (x - 7)(x + 2) = 0

• (x - 7)(x - 2) = 0

• (x + 7)(x + 2) = 0

Solve by factoring!

• -2, 4

• -8

• ±8

• No real solution

A new high school gym is painting the gym floor to represents the boundaries of a volleyball court. The court is shaped like a rectangle and has an area of 162 meters. The length of the court is 9 meters greater than the width. The situation can be represented by the equation w2 + 9w- 162 = 0. What is the width of the volleyball court in meters?
