Answer 1

Given:

The polynomial is:

`P(x)=ax+b`

To find:

Whether
`x=-(b)/(a)` is a zero of the given polynomial or not.

Solution:

We have,

`P(x)=ax+b`

Putting
`x=-(b)/(a)`, we get

`P(-(b)/(a))=a(-(b)/(a))+b`

`P(-(b)/(a))=-b+b`

`P(-(b)/(a))=0`

Since the value of the given polynomial is 0 at
`x=-(b)/(a)`, therefore
`x=-(b)/(a)` is a zero of the given polynomial.
