Beispiel Nr: 24
$(ax - b)^{2} = a^{2}x^{2} - 2\cdot a\cdot b \cdot x+ b^{2} \\ (a - b)^{2}\\ \textbf{Gegeben:} \\ (5\frac{1}{3}x - \frac{1}{2})^{2}\\ \\ \textbf{Rechnung:} \\\text{2. Binomische Formel} \\(5\frac{1}{3}x-\frac{1}{2})^{2}=\left(5\frac{1}{3}\right)^{2}x^{2}-2\cdot5\frac{1}{3}\cdot\frac{1}{2}\cdot x+\left(\frac{1}{2}\right)^{2} \\(5\frac{1}{3}x-\frac{1}{2})^{2}=28\frac{4}{9}x^2-5\frac{1}{3}x+\frac{1}{4} $
