Solve Quadratics by Factoring

What is the first step in solving 
(x + 2)(x - 3) = 0      ?

• Plug in zero for x
• Solve for x
• FOIL
• Set each binomial factor equal to zero

x²+4x-32=0

• x= -8, 4

• x= 8, -4

• x= -8, -4

x²=18x-81

• x= -9, -9

• x= 9, 9

• x= -9, 9

x²-7x=0

• x= 0, -7

• x= 0, 7

What are the factors AND solutions of x² + 2x – 3 = 0

• (x - 2)(x + 1); x=2, x=-1
• (x + 1)(x - 3); x=-1, x=3
• (x + 2)(x - 1); x=-2, x=1
• (x - 1)(x + 3); x=1, x=-3

81x²=25

• x= 5/9, -5/9

• x= -5/9, -5/9

• x= 5/9, 5/9

Solve by factoring: x² + 3x - 18 = 0

• x = -3 and x = 6
• x = 3 and x = -6
• x = -9 and x = 2
• x = 9 and x = -2

Solve using the Zero-Product Property.

7x(x − 6) = 0

• x =7 and x = −6

• x = 0 and x = 6

• x = 0 and x = −6

• x = 7 and x = 6
