Question

(ii) Check whether -2 and 2 are zeroes of the polynomial x+2.​

Answer 1

Answer:

We have to check whether - 2 and 2 is zero of the polynomial or not for that we have to put -2 and 2 as value of x and if the result comes zero then it will be the zero of the polynomial. Lets solve it.

First condition :

Putting -2 as a value of x :

$x + 2$

$( - 2) + 2$

$- 2 + 2$

$0$

As the result coming zero so -2 is a zero of the polynomial.

Second condition :

Putting 2 as a value of x :

$x + 2$

$2 + 2$

$4$

As the result is not coming zero so 2 is not a zero of the polynomial.

Ans. -2 is a zero of the polynomial but 2 is not a zero of the polynomial.

Hope it helps.
