WK 2 Lesson 3 (16/1/13) Division of Polynomials

Revision on polynomials
Polynomial
▻ variable x is a mathematical expression involving a sum of terms, each in the form axⁿ (n ∈ ℤ⁺), where a is a coefficient to the power of n, a non-negative integers.

Method 1 - comparing coefficient
3x² + 4x = Ax² + (B + 1)x
compare coef.
A = 3 , B = 3

Method 2 - numerically
3x² + 4x = Ax² + (B + 1)x
if x = 1, 3 + 4 =  A + (B + 1) ---- 1
if x = -1, 3 - 4 = A - (B + 1) ---- 2


Division of polynomials
Dividend ≣ Divisor x Quotient + Remainder
