• -1/2 and -6
• -2 and -6
• 3 and -6

What are the solutions?

• 0 and 8
• -2 and -4
• 3 and -1
• 2 and 4

What is another word that describes the zeroes of a quadratic function?  

• y-intercepts
• vertex
• x-intercepts
• maximum

How many zeros does this parabola have? 

• 3
• 2
• 0
• 1

What are the x- intercepts?

• x= 0 and x= -4
• x= 0 and x= 4
• y= 0
• x= 2

Calculate the roots of the quadratic.

• x = 6 and 3

• x = 1 and 0

• x = 0 and 3

• x = 3 and 1

What are the zeros of x²+9x+14

• 2, 7
• -2, -7
• 2, -7
• -2, 7

• Yes, the solutions would be x = 0.333, x = 0.667

• Yes, the solution would be x = 1

• No, there are no real solutions because there are no x-intercepts.
