CP quadratics

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

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

What  are the solutions of this graph?

• -2 and 3
• -1/2 and -6
• -2 and -6
• 3 and -6

What are the solutions?

Solve by factoring.
z² - 18z + 81 = 0

• z = 9
• z = -9
• z = 9 or z = -9

Solve by factoring.
z² - 6z - 27 = 0

• z = 3 or z = 9
• z = 3 or z = -9

You are given the factored equation  $\left(x+8\right)\left(x-2\right)=0$  . What is the next step to solve for x.

• Set  $x+8=0$  and $x-2=0$  

• Nothing the solution is  $x=8$  and  $x=-2$  

• Multiply  $\left(x+8\right)\left(x-2\right)$  

• Choose  $x+8$  or  $x-2$  and write a musical about them

Solve  $\left(x+2\right)\left(x-11\right)=0$  for x.

•  $x=-2$  or  $x=-11$  

•  $x=2$  or  $x=-11$  

•  $x=2$  or  $x=11$  

•  $x=-2$  or  $x=11$
