Cam divided (x^4 + 3x^2 - 4x - 2) by factor of (x-2) using synthetic division. Which best describes his mistake? Options: Cam wrote the remainder incorrectly, Cam did not use a zero place holder for the x^3 term, Cam added instead of subtracting the rows, Cam should have used -2 as his division since the factor was x-2.

Back
