Beispiel Nr: 16
$\begin{array}{l} (ax+ b)\cdot (ax - b) = a^{2}x^{2} - b^{2} \\ (a + b)\cdot (a - b)\\ \textbf{Gegeben:} \\ (\frac{2}{5}x + 2)(\frac{2}{5}x - 2)\\ \\ \textbf{Rechnung:} \\\text{3. Binomische Formel} \\(\frac{2}{5}x+2)(\frac{2}{5}x-2)=\frac{2}{5}^{2}x^{2}-2^{2} \\(\frac{2}{5}x+2)(\frac{2}{5} x-2)= \frac{4}{25}x^2-4 \end{array}$
