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{1. Binomische Formel} \\(5\frac{1}{3}x+\frac{1}{2})^{2}=\left(5\frac{1}{3}\right)^{2}x^{2}+2\cdot 5\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} $
