Beispiel Nr: 23
$\begin{array}{l} (ax+ b)\cdot (ax - b) = a^{2}x^{2} - b^{2} \\ (a + b)\cdot (a - b)\\ \textbf{Gegeben:} \\ (1\frac{2}{13}x + 9)(1\frac{2}{13}x - 9)\\ \\ \textbf{Rechnung:} \\\text{3. Binomische Formel}
\\(1\frac{2}{13}x+9)(1\frac{2}{13}x-9)=1\frac{2}{13}^{2}x^{2}-9^{2}
\\(1\frac{2}{13}x+9)(1\frac{2}{13} x-9)= 1,33x^2-81
\end{array}$
