CBSE Class 10 Maths Revision Notes Chapter 2 Polynomials

  1. Geometrical Meaning of the Zeroes of a Polynomial
  2. Zeroes and Coefficients of a Polynomial
  3. Division Algorithm for Polynomials
  4. Monomials: Algebraic expression with one term is known as Monomial.
  5. Binomial: Algebraic expression with two terms is called Binomial.
  6. Trinomial: Algebraic expression with three terms is known as Trinomial.
  7. Polynomials: All above mentioned algebraic expressions are called Polynomials.
  8. Polynomials of degrees 1, 2 and 3 are called linear, quadratic and cubic polynomials respectively.
  9. A quadratic polynomial in x with real coefficient is of the form  ,where a, b, c are real numbers with  .
  10. The zeroes of a polynomial p(x) are precisely the x–coordinates of the points where the graph of y = p(x) intersects the x-axis i.e. x = a is a zero of polynomial p(x) if p(a) = 0.
  11. A polynomial can have at most the same number of zeros as the degree of polynomial.
  12. For quadratic polynomial 

Sum of zeroes =
Product of zeroes = 
10. In a cubic polynomial , if  are the zeroes of the polynomial, then



11. The division algorithm states that given any polynomial p(x) and polynomial g(x), there are polynomials q(x) and r(x) such that :

where r(x) = 0 or degree of r(x) < degree of g(x).
Or          Dividend = Divisor x Quotient + Remainder
If r(x) = a zero polynomial, then p(x) is said to be completely divisible by g(x), i.e., g(x) is a factor of p(x).
