Maths in Class 10: Polynomial

Introduction to Polynomials:

In class 10 maths 2.2 solutions A polynomial is an algebraic expression consisting of variables and coefficients, combined using addition, subtraction, and multiplication, but not division by a variable. It’s expressed in the form:



  • ��,��−1,…,�1,�0 are coefficients.
  • is the variable.
  • is a non-negative integer and is the degree of the polynomial.

Types of Polynomials:

  1. Linear Polynomial: Degree 1. Example: 2�+3.
  2. Quadratic Polynomial: Degree 2. Example: 3�2−5�+2.
  3. Cubic Polynomial: Degree 3. Example: �3+2�2−�+5.
  4. Quartic Polynomial: Degree 4. Example: 4�4−3�2+2�−1.
  5. Quintic Polynomial: Degree 5. Example: 5�5−�3+4�2−2�+7.
  6. Higher-Degree Polynomials: Degree more than 5.

In class 10 maths 2.2 solutions Operations on Polynomials:

  1. Addition and Subtraction: Combine like terms.
  2. Multiplication: Distributive property.
  3. Division: Long division or synthetic division.

Special Polynomials:

  1. Zero Polynomial: �(�)=0.
  2. Constant Polynomial: Degree 0, �(�)=�.
  3. Monomial: A polynomial with only one term.
  4. Binomial: A polynomial with two terms.
  5. Trinomial: A polynomial with three terms.

Factoring Polynomials:

  • Common Factor: Factor out the greatest common factor.
  • Difference of Squares: �2−�2=(�+�)(�−�).
  • Perfect Square Trinomial: �2+2��+�2=(�+�)2.
  • Sum or Difference of Cubes: �3±�3=(�±�)(�2∓��+�2).
  • Factoring by Grouping: Group terms and look for common factors.

In class 10 maths 2.2 solutions Polynomial Equations:

Solving polynomial equations involves finding the values of the variable that make the polynomial expression equal to zero.

Remainder Theorem and Factor Theorem:

  • Remainder Theorem: If a polynomial �(�) is divided by �−�, the remainder is �(�).
  • Factor Theorem: If �(�)=0, then �−� is a factor of �(�).

Roots and Zeros:

  • Roots: Values of that make �(�)=0.
  • Zeros: Same as roots.

Synthetic Division:

A method to divide polynomials by binomials of the form �−�.

Graphs of Polynomials:

  • Degree and Behavior: The degree determines the behavior of the polynomial at its ends.
  • Turning Points: Locations where the graph changes direction.
  • End Behavior: Determined by the leading term.
