Zeroes of Polynomial - Part 2

Zeroes of Polynomial - Part 3

Zeroes of Polynomial - Part 4

Zeroes of Polynomial - Part 5

For polynomial  p(x) ,

If  p(a) = 0

Then x = a is the zero of polynomial

 

Let us take an example

 

Let  p(x) = 5x 3 − 2x 2 + 3x  − 6

For x = 1

    p(1) = 5(1) 3 − 2(1) 2 + 3(1)  − 6

            = 5 − 2 + 3 − 6

    = 5 + 3 − 2 − 6

    = 0

 

So p(1) = 0 for x = 1

∴ x = 1 is a zero of p(x)

 

Next, we will learn how to find zeroes of a polynomial
