Dividing Polynomials

x³-3x²-10x+24 ÷ x+3

• x²-7x+5

• x-8

• x²-6x+8

• x+9

Divide:
(9x² + 6x)  ÷ 3x

• 3x + 2

• 3x² + 2x

Which method would be better to use here based on the divisor given?

• Long division

• Synthetic division

Divide using synthetic division or long division:

(2x³ + 4x² - 5) by (x + 3).

• 2x² + 2x - 4 R(-12)

• 2x² - 2x + 6 R(-23)

• 2x² - 2x + 8 R(-20)

• 2x² - 4x + 1 R0

Solve by using long division: (6b² - 5b - 52) ÷ (3b - 10)

• 2b - 5 +2/(3b - 10)

• 2b + 5 - 2/(3b - 10)

• 18b -15 + 3/(3b - 10)

• -2b +15 +2/(3b - 10)

Which term is missing in this problem?

• x³

• x²

• x

What should be the order of the polynomial coefficients if using synthetic division? (3x - 4x³+ 6x⁴ + 1) / (x + 3)

• 3 0 -4 6 1

• 6 -4 3 1 0

• 6 -4 0 3 1

• -6 4 0 -3 -1
