Question
Verify whether the following zeroes of the polynomial are indicated against them.
p(x) = 5x – π, `x = 4/5`
Solution
If `x = 4/5` is a zero of polynomial p(x) = 5x − π, then `p(4/5)` should be 0.
Here, `p(4/5) = 5(4/5) - π`
= 4 - π
As `p(4/5) ≠ 0`,
Therefore, x = `4/5` is not a zero of the given polynomial.
