Question

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

`f ( x ) = 3x +1, x = - 1/3`

Solution

`f ( x ) = 3x +1, x = - 1/3`

We have

`f ( x) = 3x +1`

Put

`x=-1/3⇒f(-1/3)=3xx(-1/3)+1=-1+1=0`

`∴x=-1/3 `is root of `f(x)=3x+1`

  Is there an error in this question or solution?
