Factoring by a GCF

Factor:

80x⁵ - 70x² - 60x⁷

• 2x²(80x³ - 70 - 60x⁶)

• 10x²(80x⁴ - 70x - 60x⁶)

• 10x²(8x³ - 7 - 6x⁵)

• 3x²(80x³ - 40 - 60x⁵)

Factor by GCF:
17xy - x

• 17(xy - x)

• y(17x - x)

• x(17y - 1)

• not factorable

Factor:
24c⁵ - 12c³

• 6(4c⁵ - 2c³)

• 12c³(2c²)

• 12c³(2c² - 1)

Find the factors

16xy - 24y

• 4y (4x - 6)

• 8y (2xy - 3y)

• 8y (2x - 3)

• 2xy (8 - 12y)

Factor completely

21x⁷y⁶ + 30x⁵y⁸ - 18x⁵y⁶

• 3xy (7x⁴y² + 10x²y⁶ - 6x)

• 3x⁵y⁶ (7y² + 10 x² - 6)

• 3x⁵y⁶ (7x² + 10y² - 6)

• 3x⁷y⁸ (7y² + 10x² - 6x²y²)

-6y + 36

• -6 (y -6)

• 6 (y + 6)

• -6 (1)

• cannot be factored
