5.5 Dividing Polynomials

• 2x - 5

• x - 4

• x + 4

• 2x + 4

Divide: 

(4x² - 24x + 35) / (2x - 5)

• 2x - 7
• 2x - 12
• 2x + 12
• 2x + 7

(5p²+5p-26)÷(p+3)

• 5p-10, R 4

• 5p-12, R 1

• 5p-13, R 8

• 5p-10, R 5

What is the remainder when a³ - 4 is divided by a+2? 

• -2
• -6
• -12
• 0

What is the proper way to write the answer for the following problem?

• 2x³-x²-25x+12

• 2x⁴-x³-25x²-12x+0

• 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.

(2x³ + 7x² - 6x - 8) ÷ (x + 4)

• 2x² - x - 2
• 2x³ - x² - 2x
• 2x² + 15x + 54 + 208/x+4
• 2x³ + 15x² + 54x + 208

• x - 7
• x² - 7
• x + 7
• x² + 3x - 54
