A2. The expression $\operatorname{Izraz}\left(a^{2}-4\right) \cdot(a-2)^{-1}$ is equal to the expression:
(A) $a-2$
(B) $(a-2)^{2}$
(C) $a+2$
(D) $(a+2)^{2}$
(E) $a-4$
A2. The expression $a^{2}-4$ can be factored as $(a+2)(a-2)$. The entire expression can be written in the form of a fraction $\frac{(a+2)(a-2)}{a-2}$, we simplify it and get $a+2$.
