Factoring Practice

Factor completely:

3x² +48

• (x+4i)(x-4i)

• 3(x-4i)(x+4i)

• 3(x²+16)

• 3(x+4)(x-4)

Factor Completely:

x² + 36

• (x + 9)(x - 4)

• (x - 6i)(x - 6i)

• (x - 9i)(x + 4i)

• (x + 6i)(x - 6i)

Factor this sum of cubes:
2x³ + 128

• 2(x³ + 64)
• (x + 4)(x² - 4x + 16)
• 2(x - 4)(x² + 4x + 16)
• 2(x + 4)(x² - 4x + 16)
