Factor the GCF
56a³-8a

• 8a²(56a³-8a)
• 8a(7a²-1)
• 8a(7a³-a)
• 8a²(35a²-a)

Factor the GCF

2n²-8n³

• 2n²(n-4n²)

• 2n²(1-4n)

• 2n³(10-8n²)

• 3n(1-4n)

Factor the GCF

45xy + 15x³y + 10y

• 5y (9xy + 3x² + 2y)

• 5xy (9 + 3x² + 2)

• 5x (9y + 3xy + 2)

• 5y (9x + 3x³ + 2)

Factor the GCF

10x³ + 30x² + 20xy

• 5x(2x² + 6x + 4y)

• 10x(x² + 3x + 2y)

• 10x(x² + 3x + 2)

• 5x(2x² + 6x + 4)

Factor the GCF

15x²y⁴ + 21x³y⁷

• xy(15xy³ + 21x²y⁶)

• 3xy(5xy³ + 6x²y⁶)

• x²y⁴(15 + 21xy³)

• 3x²y⁴(5 + 7xy³)

Difference of Squares

4a² - 25
