Perform the following polynomials divisions: (12 marks)

(x2 - 7x - 12) ÷ (x + 2)

(x3 + x2 – 3x + 1) ÷ (x – 1)

(3x3 + 5x2 – 3x – 5) ÷ (x + 1)

(x4 - 3x3 + 3x + 2) ÷ (x - 2)

Based on the results of question 1, what do you notice when the divisor is a factor of the polynomial? (1 mark)

correction

(x^2 - 7x - 12) ÷ (x + 2)

(x^3 + x^2 – 3x + 1) ÷ (x – 1)

(3x^3 + 5x^2 – 3x – 5) ÷ (x + 1)

(x^4 - 3x^3 + 3x + 2) ÷ (x - 2)

(x^2 - 7x - 12) ÷ (x + 2) = (x-9) remainder 6

(x^3 + x^2 – 3x + 1) ÷ (x – 1) = (x^2+2x-1) remainder 0

(3x^3 + 5x^2 – 3x – 5) ÷ (x + 1) = 3x^2+2x-5 remainder 0

(x^4 - 3x^3 + 3x + 2) ÷ (x - 2) = x^3-x^2-2x-1 remainder 0
