Completing the Square Practice

Identify the 'b' value: y = 16x² -8x -24

• 16
• -8
• 8
• -24

Identify the 'b' value in this equation

x² = 9 - 4x (*be sure to get it equal to zero!)

• 4

• -9

• -4

• 9

Solve the equation by completing the square.
 $x^2+14x-15=0$  

•  $x=-1,\ x\ =\ 15$  

•  $x=5,\ x=-3$  

•  $x=1,\ x=-15$  

•  $x=-5,\ x=3$
