Use synthetic division: (2x³ - 5x² + 3x + 7) ÷ (x - 2)

• 2x³ - x² + x + 9

• 2x² - x + 1

• 2x² - x + 1 + 9/x-2

• 2x² - 9x - 15 - 23/x-2

Is (x - 3) a factor of (3x³ - 10x² - x - 12) ? Explain.

• Yes, it is a factor, because -12 divides evenly by 3.

• No, it is not a factor, the remainder is not 0.

• No, it is not a factor because the remainder is 0.

• Yes, it is a factor. We can divide

  (3x³ +10x² - x -12) by (x - 3).
