Solving by Factoring

Solve:

k² - 2k - 24 = 0

• k = -4, 6

• k = -4, -6

• k = -6, 1

• k = 4, -6

Solve:

3x² + 18x +15 = 0

Hint: Factor GCF first.

• x = 3, 2

• x = 5, 1

• x = -5, -1

• x = -3, -2

Solve
x² + 13x + 12 = 0

• x = -1, x = -12
• x = -1, x = -24
• x = -2, x = -6
• x = -2, x = -12

Solve.

n² - 2n = 0

• n = 2, 0

• n = -2, 0

• n = 2

• n = 0

Solve by factoring:

5x² + 13x + 6 = 0

Solve
 2x² - 3x - 2 = 0

• x = 1, x = -1
• x = -1/2, x = 2
• x = 1/2, x = 2
• x = 1/2, x = 1

Solve
 3x² + 5x - 12 = 0

• x = -4/3, x = 3
• x = 4/3, x = -3
• x = -1, x = 4
• x = 1, x = -4

Solve
4x² - 25x + 25 = 0

• x = 5, x = -5
• x = -5, x = -5/4
• x = 5, x = 5/4
• x = -2, x = -1/9
