• 16
• -8
• 8
• -24

What is the vertex of the graph?

• (2, 0)

What should you do first in solving this equation?
x² + 6x - 13 = 3

• Get factored form
• Write down: a=1, b=6, c=-13
• Make it equal 0 by subtracting 3 on each side
• Type it all in a calculator.

Find the solutions of the quadratic equation: 
(x+10)(x-2) = 0

• 10 and 2
• -2 and 10
• -10 and 2
• -2 and -10

Solve the equation using the zero product property.
(x- 9)(x + 3) = 0

• x = 3 and x = 9

• x = 3 and x = -9

• x = -3 and x = 9

• x = -3 and x = -9

Convert x² +6x +9 to factored form and identify the solutions.

• (x+3)(x+3); x = -3

• (x+3)(x+3); x = 3

• (x-3)(x-3); x = 3

• (x-3)(x-3); x = -3

• x = 4 and x= -1

• (-4, 1)

• x = -4 and x = 1

• (4, 0) (-1, 0)

Factor and determine the solutions for this quadratic function:

x² + 44 = -15x

• x = -8 and x = 2

• x = -7 and x = 5

• x = -11 and x = -4

• x = -22 and x = -2
