Factoring Methods

Factor completely:

3x² + 18x +15

Hint: Factor GCF first.

• 3(x² + 5x + 5)

• (x + 5)(x + 1)

• 3(x + 5)(x + 1)

• 3(x - 5)(x - 1)

Factor Completely: 5v² - 30v + 40

• (5v - 8)(v - 5)

• (5v + 5)(v - 8)

• 5(v - 4)(v - 2)

• 5(v + 8)(v - 5)

Factor completely.
3x² - 9x -120

• 3(x - 8)(x + 5)

• 3(x + 8)(x - 5)

• (3x + 8)(x - 5)

• (3x - 8)(x + 5)

Factor (Easy Trinomial):
x² - 2x - 15

• (x - 5)(x + 3)

• (x + 3)(x - 5)

• (x - 3)(x - 5)

• (x - 15)(x - 2)

Factor (Grouping):
20x³ - 25x² + 4x - 5

• (5x² - 5) (4x + 1)

• 5 (x² - 1) (4x + 5)

• (5x² + 1) (4x - 5)

• (5x² + 1) (4x - 1)

Factor (Harder Trinomial):
2x² - 5x - 3

• (2x + 1) (x - 3)

• (2x - 1) (x + 3)

• (2x - 1) (x + 6)

• (x + 1) (2x - 3)

Factor (Harder Trinomial):
6x² + 7x - 3

• (3x - 1) (2x + 3)

• (3x + 1) (2x - 3)

• (6x + 1) (x - 3)

• (2x + 1) (3x - 3)

Factor (Harder Trinomial):
4x² - 8x + 3

• (2x - 1) (2x - 3)

• (2x + 1) (2x + 3)

• (4x + 1) (x + 3)

• (4x - 1) (x - 3)

Factor (Easy Trinomial):
x²  + 8x - 20

• (x + 10)(x - 2)

• (x + 4)(x + 5)

• (x - 10)(x + 2)
