Remainder Theorem

1. According to Remainder Theorem: Let p(x) be any polynomial and a be any real number. If p(x) is divided by the linear polynomial x - a, then the remainder is p(a).

2. If p(x) is divided by  (x + a), then remainder is p(-a).

3. If p(x) is divided by (ax -b) then remainder is p(b/a).

4. If p(x) is divided by (ax + b), then remainder is p(-b/a).

5. In above cases, -a, b/a and -b/a are the zeros of the divisors x + a, ax-b and ax+b respectively.

Synthetic Fibres and Plastics

NCERT Chapter Solutions and Q & A

Q1: Explain why some fibres are called synthetic?

Answer: Some fibres are called synthetic because they are not made from natural fibres. Instead, they are made by chemical processing of petrochemicals. Synthetic fibres are made up of very large units called polymers. Some of the synthetic fibres are rayon, nylon and acrylon.

ZEROS (ROOTS) of a POLYNOMIAL

1. A zero of a polynomial p(x) is a number c such that p(c) = 0.
   OR x = c (or x -c = 0 ) is called the root of the polynomial equation p(x).

2. If p(x) = ax + b, a ≠ 0, is a linear polynomial, x = -b/a, is the only zero of p(x), i.e., a linear polynomial has one and only one zero.

3. A zero of a polynomial need not be 0.

4. 0 may be a zero of a polynomial.

5. Every linear polynomial has one and only one zero.

6. A polynomial can have more than one zero.

7. Zeros of the polynomial are also called roots of the polynomial.
