Question

Verify whether the indicated numbers is zeroes of the polynomials corresponding to them in the following case:

`f ( x ) = 5x - pi , x = 4/5`

Solution

We know `f ( x ) = 5x - pi , x = 4/5`

put `x=4/5⇒ f (4/5)=5xx4/5-pi=4-pi≠0`

`∴x=4/5 `is not a root of `f(x)=5x-pi`

  Is there an error in this question or solution?
