The sub-topics discussed in detail in the chapter- Polynomials are as follows. Mayhs of the polynomial. Types of ch 2 maths class 10 extra questions 2??. Zeroes of the polynomial.

Relationship between Coefficients of the polynomial and its roots. Division of a polynomial with another polynomial using the long division method. Degree of the polynomial is defined by the highest power of the polynomial. The degree is a representation method of the polynomial. For a polynomial p xwhich is a polynomial of a single variable, the degree is depicted by:. Degree of the polynomial refers to the highest power of the variable.

Depending upon the degree of the polynomial, it can be categorised into:. Linear Polynomial - Polynomial of degree one. Ex- 5x - 1. Quadratic Polynomial - Polynomial of the second degree. Cubic Polynomial - Polynomial of degree.

Quartic Polynomial - Polynomial of the extrq degree. Polynomials are algebraic expressions made up of terms that are connected using mathematical operators.

Polynomials can also be differentiated based chh the number of terms:. Monomial - Polynomials with only a single term. Binomial - Polynomials with two terms. Trinomial - Polynomial made up of three terms.

The number of zeros of a polynomial is dependent upon the degree of the polynomial. A polynomial of degree 1 has only one zero. A polynomial of degree 2 has two zeros. A questiona of degree 3 has 3 zeros. Zero of a linear polynomial is given by the formula:. Zero of a quadratic polynomial can be found using hit and trial method but often this is tiresome so we use the quadratic formula to find the zeros of a quadratic polynomial.

The zeros of the polynomial are:. Download the list of important questions for class 10 maths polynomials to practice questions from each of the topics.

Question 9. Question Verify that the numbers given along side of the cubic polynomials below are their zeros. Also, verify the relationship between the zeros and coefficients in each case:. Thus, the relationship between the zeroes and the coefficients is verified.

Concept insight: The zero of a polynomial is that value of the variable which makes the polynomial 0. Remember that there are three relationships between the zeroes of a cubic polynomial and its coefficients which involve the sum of zeroes, product of all zeroes and the product of zeroes taken two at a time.
