Beispiel Nr: 10
$\begin{array}{l} (ax - b)^{2} = a^{2}x^{2} - 2\cdot a\cdot b \cdot x+ b^{2} \\ (a - b)^{2}\\ \textbf{Gegeben:} \\ (3x - 1\frac{2}{3})^{2}\\ \\ \textbf{Rechnung:} \\\text{2. Binomische Formel} \\(3x-1\frac{2}{3})^{2}=3^{2}x^{2}-2\cdot3\cdot1\frac{2}{3}\cdot x+\left(1\frac{2}{3}\right)^{2} \\(3x-1\frac{2}{3})^{2}=9x^2-10x+2\frac{7}{9} \end{array}$
