Camille divided (x⁴ + 3x² - 4x - 2) by factor of (x-2) using synthetic division. Her work is shown above. Which best describes his mistake?

• Cam wrote the remainder incorrectly.

• Cam did not use a zero place holder for the x³ term.

• Cam added instead of subtracting the rows.

• Cam should have used -2 as his division since the factor was x-2.
