In this video, examples on Factoring polynomial are explained.Zeros of polynomial are determined by equating each factor of polynomial to zero.Sum and Productof zeroes is find out with Coefficient of x,Coefficient of x^2 and constant term of polynomial.Verification of obtain results is done.

00:02 (ii) Find the zeros of a quadratic function 4s^2 – 4s + 1 by factoring

04:10 Factoring quadratic polynomial.Factorization method

00:58 zeroes of polynomial.

01:25 Relationship between Zeroes and Coefficients of a Polynomial

01:35 Sum of zeroes = -(Coefficient of x )/(Coefficient of x^2)

02:38 Product of zeroes = (Constant term)/(Coefficient of x^2).

03:04 (iii) Find the zeros of a quadratic function 6x^2 – 3 – 7x by factoring

03:55 Factoring quadratic polynomial

04:45 zeroes of polynomial.

04:58 Relationship between Zeroes and Coefficients of a Polynomial

05:33 Sum of zeroes = -(Coefficient of x )/(Coefficient of x^2)

06:18 Product of zeroes = (Constant term)/(Coefficient of x^2).

Zeroes of the polynomial are the values of variable “x” when the polynomial equals zero.

Factoring polynomial: To find factors of Quadratic polynomial

If p(x) is a polynomial in x , and if k is any real number, then the value obtained by replacing x by k in p(x), is called the value of p(x) at x=k , and is denoted by p(k).Real number k is said to be a zero of a polynomial p ( x ), if p ( k) = 0.

Zeros of a polynomial. Relationship between zeros and coefficients of quadratic polynomials.

Sum of zeros polynomial = -(Coefficient of x )/(Coefficient of x^2)

Product of zeros polynomial = (Constant term)/(Coefficient of x^2)
