- By a monomial
E.g.; Divide the polynomial p(x) by the monomial 2x, where,
p(x) = 2x3 + 4x2 - 5x – 1
Solution
p(x)2x=2x3+4x2-5x-12x=2x32x+4x22x+-5x2x+-12x=x2+2x-52-12x
- By another polynomial
This division is often done by the long division method.
Example; the polynomial p(x) is given by, p(x) = 2x3+3x2-4x-20, find; p(x) ÷ (x – 2)
Solution
2x2+7x+10
X - 2/2x3+3x2-4x-20
7x2 – 4x
10x – 20
_ _
∴ p(x) ÷ (x – 2) = 2x2+7x+10
