divide the polynomial p x by the polynomial g x...

Question:
Divide the polynomial p(x) by the polynomial g(x) and find the quotient and remainder in each of the following :
(i) p(x) = x³– 3x²+ 5x – 3, g(x) = x²– 2 (ii) p(x) = x⁴– 3x²+ 4x + 5, g(x) = x²+ 1 – x (iii) p(x) = x⁴ – 5x + 6, g(x) = 2 – x²

Answer:

(i) Given ,

Dividend = p(x) = x² – 3x²+ 5x – 3

Divisor = g(x) = x²– 2

Quotient = x – 3

Reminder = 7x – 9

(ii) Given,

Dividend = p(x) = x⁴– 3x²+ 4x + 5

Divisor = g(x) = x² + 1 – x
