GCF and Factor by Grouping Pre-Assesment

Factor out the GCF

3x³ + 9x

• 3x (x² + 3)

• 3x ( x³ + 9)

• x (3x² + 9)

• 3x (x³ + 3x)

Factor:
10a⁴+16a+10a²

• 2a(5a³⁺8+5a)
• 2a⁴(5a+8a²+5a³)
• 2a⁴(10+16a+40a²)
• 3a³(5+8a+a²)

Factor out the GCF

21x⁷y⁶ + 30x⁵y⁸ - 18x⁵y⁶

• 3xy (7x⁴y² + 10x²y⁶ - 6x)

• 3x⁵y⁶ (7y² + 10 x² - 6)

• 3x⁵y⁶ (7x² + 10y² - 6)

• 3x⁷y⁸ (7y² + 10x² - 6x²y²)

Factor by grouping:

x³ + 7x² - 2x - 14

• (x² - 2)(x - 7)

• (x² + 2)(x - 7)

• (x² + 2)(x + 7)

• (x² - 2)(x + 7)

Factor by grouping:

5n³ - 10n² + 3n - 6

• (5n² + 3)(n - 2)

• (5n² - 3)(n - 2)

• (5n³ + 3)(n - 2)

• 10n(n² - 6)
