Question

7 is a zero of a polynomial s(x).

Answer 1

Answer:

We know that the zero of the polynomial is defined as any real value of x, for which the value of the polynomial becomes zero.

For example:

Let f(x)=−4x+7 be the polynomial.

To find the zero of the polynomial, we substitute f(x)=0 as shown below:

f(x)=−4x+7

⇒0=−4x+7

⇒4x=7

⇒x=

4

7

.

Therefore,

4

7

is the zero of the polynomial f(x)=−4x+7, which contradicts the statement that zero of a polynomial is always zero.

Hence, the zero of a polynomial is not always zero.
