Question

Check whether -2 and 2 are zeroes of the polynomial x+2

Answer 1

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

Explanation:

A value of x is a zero of a polynomial if when it is substituted for x in the polynomial, it makes the polynomial evaluate to zero.

The polynomial is x + 2

Let x = -2:

x + 2 = -2 + 2 = 0

-2 is a zero of the polynomial.

Let x = 2:

x + 2 = 2 + 2 = 4

2 is not a zero of the polynomial.
