Factoring and Solving GCF

Factor
x² +17x - 60

• (x - 20)(x + 3)

• (x + 12)(x - 5)

• (x - 12)(x + 5)

• (x + 20)(x - 3)

Factor by using GCF:
8n³ + 2n²

• 2n²(4n-1)

• 2n²(4n + 1)

• n²(8n+2)

• 3n(4n+1)

-10xy⁹z + 8y³z⁵

• -2y⁴z(20xy⁶ - 4z⁴)

• -2y³z(5xy⁶ - 4z⁴)

• -2y³z(5xy⁶z - 4z⁵)

• -2y³z(5xy⁶z - 8z⁴)

-8x²y² + 32yz + 40y

• -8z(x² - 4z - 1)

• -8y(4x²y² - 16yz - 20y)

• -8y(x²y - 4z - 5)

• -4y (2x²y - 40z - 10)

Solve for x:

3x² - 9x = 0

• x = 3

• x = 0, 3

• x = -3, 9

• x = 9
