FAQ (Frequently Asked Questions)

Q 1: What are the important terms of a polynomial?


  • A term might either be a variable or a single digit or it also could be a sequence of the variable with digits.

  • The degree of the polynomial is the most distinguished power of the variable in a polynomial.

  • A polynomial of degree 1 will be termed as a linear polynomial.

  • A polynomial of degree 2 will be described as a quadratic polynomial.

  • A polynomial of degree 3 is termed as a cubic polynomial.

  • A polynomial of 1 term is termed as a monomial.

  • A polynomial of 2 terms is termed as binomial.

  • A polynomial of 3 terms is termed as a trinomial.

  • A real number ‘a’ is a zero of a polynomial p(x) if p(a) = 0, where a is also termed as root of the equation p(x) = 0.

  • A linear polynomial in one variable holds an individual zero, a polynomial of a non-zero constant has no zero, and every real character is a zero of the zero polynomial.

Q 2: Give a brief description of the topic.

Ans: Polynomial is acquired from the word “poly” which means “many” and the word “nominal” refers to “term”. In Math subject, a polynomial expression consists of variables which are also known as coefficients and indeterminates. The coefficients require the operations of addition, subtraction, non-negative integer exponents of variables and multiplication. 

Polynomials are utterances with one or more phrases with a non-zero coefficient. A polynomial can also have one or more than one number of terms. In the form of a polynomial, each utterance in it is known as a term.  Suppose x2 + 4x+ 2 is polynomial, then the expressions x2, 4x, and 2 are the terms of the polynomial.  Each term of the polynomial has a coefficient. For example, if 4x+1 is the polynomial, then the coefficient of x is 4.

Q 4: What are the topics that are covered in this chapter?

Ans: Polynomial is an algebraic expression which includes constants, variables and exponents. It is the expression where the variables have just certain elemental powers. The topics that are covered in this chapter are:

  • Introduction

  • Polynomials in One Variable

  • Zeros of Polynomials

  • Remainder Theorem

  • Factorisation of Polynomials

  • Algebraic Identities

Polynomial expressions are algebraic equations which will have two or more terms with the equal variables of different exponents. This is one of the notable topics for class 9 Mathematics, which students require to learn in order to gain profound knowledge about complex algebraic expressions. Mathematics is one of those subjects that serve as a foundation of numbers, analysis, figures and logic.
