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.

Mr. Dye was trying to do synthetic division. Looking at his work, what mistake did he make? Silly Mr. Dye

• He did nothing wrong. That is correct.

• He added the numbers when he should have subtracted.

• $-5$ should be the number in the box.

• He put the coefficient numbers in the incorrect order.

Arwen is solving the problem below. She set up and solved the synthetic division problem correctly (look at picture). What is the proper way for her to write the answer? $\left(2x^4-9x^3-21x^2+88x+48\right)\div\left(x-4\right)$  

•  $2x^3+x^2+25x+12$  

•  $2x^4+x^3+25x^2+12x\ +0$  

•  $2x^3-x^2-25x-12$  

•  $2x^4-x^3-25x^2-12x\ -0$
