(A) Let the polynomial be $p(x) = x + 2$.To check if $x = a$ is a zero of the polynomial,we evaluate $p(a)$. If $p(a) = 0$,then $a$ is a zero.For $x = 2$:$p(2) = 2 + 2 = 4$.Since $p(2) 
eq 0$,$2$ is not a zero of the polynomial.For $x = -2$:$p(-2) = -2 + 2 = 0$.Since $p(-2) = 0$,$-2$ is a zero of the polynomial.Therefore,$-2$ is a zero of the polynomial $x + 2$,but $2$ is not.

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