- P(x) =
- x = 2
- Zeros of the polynomial is the value of the variable for which when replaced in the polynomial the value for the polynomial changes to zero .
- Where '
' are Real numbers and 'n' is an integer .
- To show that 2 is not a zero of the polynomial ' P(x) =
'
- We have to show that P(2)
0
- P(2) =
- P(2) = 4 + 4 +5
- P(2) = 13
- ∵ P(2) = 13
0
- ∴ 2 is not a zero of the polynomial ' P(x) =
'
