Question

Find the zero of the polynomial p(x), where p(x)=ax+1, a is not equal to 0.

Answer 1

To find the zero of a polynomial we should keep it as equals to zero
i.e..., p(x)= 0
=> ax+1=0
=>ax=-1
=> x=-1/a  

Answer 2

Polynomial

The zeroes of the polynomial are the values of x which will satisfy the equation $y=f(x)$, where $f(x)$is a function of x.

Zeroes are the value of x , which on putting into y gives the value of y as 0.

Polynomial $p(x)=ax+1$, and a is not equal to 0.

$p(x)=0=ax+1\\\\\implies ax+1=0\\\\\implies ax=-1\\\\\implies x =\frac{(-1)}{a}$

Hence on putting the value of x as  ($\frac{-1}{a}$ ), the value of polynomial $p(x)$ is 0.
