What is the green dot on the parabola called?

• maximum
• minumum
• roots
• zeros

The axis of symmetry (line of symmetry) of this parabola is...

• y=4
• y=-4
• x=4
• x=-4

What is the vertex of the graph?

HINT: Vertex is (x, y)

• (-2, 0)

• cannot be determined

• (2, -1)

• (0,-5)

Use the graph to determine the solutions.

• (-1,0) and (-3,0)
• (1,0) and (-3,0)
• (1,0) and (3,0)
• (-1,0) and (3,0)

x² - 25

HINT: Special Case, notice there is no "b term"

• ( x + 5 ) ( x - 5 )

• ( x - 5 ) ( x - 5 )

• ( x + 5 ) ( x + 5 )

• Prime

Factor:

x² + 11x + 24

HINT: What two numbers multiply to give you 24 and ADD to giver you 11?

• (x + 6)(x + 4)

• (x + 12)(x + 2)

• (x - 8)(x - 3)

• (x + 8)(x + 3)

Factor:

x² - 10x + 24

HINT: What two numbers multiply to give you 24 and ADD to giver you -10?

• (x - 6)(x - 4)

• (x + 6)(x + 4)

• (x - 12)(x + 2)

• (x - 8)(x - 3)

Factor:

x² + 2x - 24

HINT: What two numbers multiply to give you -24 and ADD to giver you 2?

• (x - 6)(x + 4)

• (x + 6)(x + 4)

• (x - 6)(x - 4)

• (x + 6)(x - 4)

p² − 5p − 14

HINT: What two numbers multiply to give you -14 and ADD to giver you -5?

• ( p + 2)( p + 7)

• ( p + 2)( p − 7)

• ( p - 2)( p − 7)

• ( p - 2)( p + 7)

What are the Zeros? (Need to factor it first)...

t² - 6t + 8

HINT: What two numbers multiply to give you 8 and ADD to give you -6. Then take the opposites or your Binomials.

• (t - 4)(t - 6)

• t = 2 & t = 4

• t = - 2 & t = - 4

• (t - 2)(t - 4)
