# Lesson 8 The Wow Factor Solidify Understanding

For each given quadratic equation:

graph the function,

state the vertex,

write the equation of the line of symmetry,

identify the stretch factor, and

indicate whether the quadratic has a maximum or a minimum.

Each of the problems contains the same number of squares with the dimensions

#### a.

What is different about them?

#### b.

How does this difference affect the expressions that represent the area?

#### c.

Describe how the arrangement of the squares and rectangles affects the factored form.

Another way to represent a quadratic expression is with an open area model. Each diagram represents both factored and standard form. For each open area model given, find the factored and standard form.
