Beispiel Nr: 18
$(ax - b)^{2} = a^{2}x^{2} - 2\cdot a\cdot b \cdot x+ b^{2} \\ (a - b)^{2}\\ \textbf{Gegeben:} \\ (8x - 1\frac{6}{13})^{2}\\ \\ \textbf{Rechnung:} \\\text{2. Binomische Formel} \\(8x-1\frac{6}{13})^{2}=8^{2}x^{2}-2\cdot8\cdot1\frac{6}{13}\cdot x+\left(1\frac{6}{13}\right)^{2} \\(8x-1\frac{6}{13})^{2}=64x^2-23\frac{5}{13}x+2,14 $
