Add or Subtract to Simplify:

(4n⁴ - 8n + 4) - (8n² + 4n⁴ + 1)

Hint: Distribute the "negative sign" into the second polynomial and then ADD them together/Combine like terms.

• -8n² - 8n + 3

• -7n² - 8n + 3

• -6n² - 8n + 3

• -7n² - 4n + 3

(2x + 3)(x² + 4x + 1)

Hint: When multiplying do not forget to ADD your exponents!!!! Use your Box Method =)

• 2x³ + 10x² + 14x + 4

• 2x³ + 11x² + 14x + 3

• -2x³ - 11x² + 14x + 5

• x³ - 11x² + 14x + 3
