Multiple Choice

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

• Cal wrote the remainder incorrectly.

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

• Cal added instead of subtracting the rows.

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