nedenispolybomy $\frac{a+6}{a^2}- \frac{1}{a^2-4} * \frac{(a+2)^2}{a}= \frac{2(a-6)}{a^2(a-2)} ; \\
1) \ \frac{1}{a^2-4} * \frac{(a+2)^2}{a}= \frac{(a+2)^2}{a(a^2-4)}= \frac{(a+2)^2}{a(a-2)(a+2)}= \\
= \frac{(a+2)}{a(a-2)}; \\
2) \ \frac{a+6}{a^2}-\frac{(a+2)}{a(a-2)}=\frac{(a-2)(a+6)}{a^2(a-2)}-\frac{a(a+2)}{a^2(a-2)}= \\
= \frac{(a-2)(a+6)-a(a+2)}{a^2(a-2)}= \frac{2a-12}{a^2(a-2)}= \frac{2(a-6)}{a^2(a-2)}$
