 $2x^2-\ 18x\ =\ 0$  

The equation is set equal to zero, what is the second step to solve using zero product property?

• Factor out the GCF

• Find 2 numbers that add to 2 and multiply to 18

• Take the square root of both sides

 $x^2\ +\ 5x\ =\ -6$  

Set the equation equal to zero.

•  $x^2+5x-6=0$  

•  $x^2+5x+6=0$ 

•  $x^2=-5x\ -6$

 $2x\left(x-\ 9\right)=\ 0$ 
What are the two equations you will create to solve using the zero product property? 

• 2x = 0

• x - 9 = 0

• 2x = 0  OR    x - 9 = 0
