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.

The total number of video cassettes sold from 1995 to 2005 at Bob’s store can be modeled by the function   $F\left(x\right)=4x^3+14x^2+200x+1560$  and the number of kinds of video cassettes in Bob’s store from 1995 to 2005 can be modeled by G(x) = 2x + 12, where x is the number of years since 1995. Which of the following expressions correctly describes the average number of each kind of video cassettes that Bob sold?

•  $2x^2+5x+96$  

•  $4x^2+5x-86$  

•  $2x^2-5x+130$
