Factor GCF and A=1

Factor out the GCF

3x³ + 9x

• 3x (x² + 3)

• 3x ( x³ + 9)

• x (3x² + 9)

• 3x (x³ + 3x)

Factor out the GCF:

a³ + a² + a

• a²(a + a + 1)

• a³(1 + a + a)

• a(a² + a + 1)

• a(a² + a)

Factor out the GCF: 2n² - 8n³

• 2n²(n - 4n²)

• 2n²(1 - 4n)

• 2n³(10 - 8n²)

• 3n(1 - 4n)

Factor out the GCF

18x³ + 81x - 27

• 9x (2x² + 9x - 3)

• 3 (6x³ + 27x - 9)

• 9 (2x³ + 9x - 3)

• 9 (2x² + 9x - 3)

Factor completely.

x² + 17x + 72

• ( x + 9 ) ( x - 8 )

• ( x - 9 ) ( x + 8 )

• ( x + 9 ) ( x + 8 )

• ( x - 9 ) ( x - 8 )

Factor out the GCF: 56a³ - 8a

• 8a²(56a³ - 8a)

• 8a(7a² - 1)

• 8a(7a³ - a)

• 8a²(35a² - a)

Factor out the GCF: 80x⁵ - 70x² - 60x⁷

• 2x²(80x³ - 70 -60x⁶)

• 10x²(80x⁴-70x-60x⁶)

• 10x²(8x³-7-6x⁶)

• 3x²(80x³-40-60x⁵)

Factor out the GCF:

• 4b³(b⁴ + b² + 4b)

• 4b³(b⁴ + 4b + 5)

• 4(b⁵ + b³ + 4b²)

• 4b²(b³ + b + 4)
