What is the proper way to write the answer for the following problem? If the dividend was a quartic.

• 2x³-x²-25x+12

• 2x⁴-x³-25x²-12x+0

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.

When dividing the polynomials should long or synthetic division be used.

(2x³ + 7x² - 6x - 8) ÷ (x + 4)

• Long Division

• Synthetic Division
