Chapter 3A Quiz

• Not Factorable 

Solve
4m² - 100 = 0

• m=25 or m=-25
• m=96
• m=5 or m =  -5
• m=-96

Solve
x² + 2x - 24 = 0

• x = -6, x = 4
• x = 6, x = -4
• x = 12, x = -2
• x = 8, x = -3

Solve for the values of x:

(2x - 1)(x + 4) = 0

• x=1/2, x= -4

• x=1/2, x= 4

• x= 1, x=-4

• x=-2.5, x=4

Find the roots of this quadratic function:

2x²-x=0

• 2 and 7

• 1/2 and 0

• 2 and 0
