Solve by Factoring Part 1 Quiz

Solve by factoring: x² - 9x + 20 = 0

• x = -4 and x = -5
• x = 20 and x = -9
• x = 4 and x = 5
• x = -4 and x = 5

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.
n² - 2n = 0

• n = 2 and 0
• n = -2 and 0
• n = 2
• n = 0

Solve
7x² = -21x

• x = 3
• x = -3
• x = 0, 3
• x = 0, -3

Solve using Zero-Product Property
(x - 11)(5x + 1) = 0

• x = 11 or x = -1/5
• x = -11 or x = -1/5
• x = 11 or x = 1/5
• x = -11 or x = 1/5

Solve by GCF factoring

5x² + 15x = 0

• x = 0, x = -3

• x = 5, x = 3

• x = 15, x = 0

• x = 3, x = 1

Solve the equation by factorising.
x² + 13x = -40

• -8, 5
• -40, -1
• 5, 8
• -8, -5
