Cam divided (x4 + 3x2 - 4x - 2) by factor of (x-2) using synthetic division. His 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.
Was this problem done correctly?
Yes
No
