• -1/2 and -6
• -2 and -6
• 3 and -6

Factor the Trinomial (GCF first):

3x² + 18x +15

• 3(x + 6)(x -1)

• 3x(x + 15)(x + 1)

What are the solutions to this equation? (x-3)(x+2)=0

• x=3,-2
• x=-3,2
• x=2,3
• x=3,2

 Solve the equation (7x+2)(5x-4)=0

• x=2  or -4
• x=2/7  or 4/5
• x=-2/7 , or 4/5
• x=-2, or 4

Solve the equation using the zero product property.
3x ( 2x - 4) = 0

• x = -1/3 or x = -2
• x = 0 or x = 2
• x = 0 or x = -2
• x = -1/3 or x = 2
