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{1. Binomische Formel} \\(8x+1\frac{6}{13})^{2}=8^{2}x^{2}+2\cdot 8\cdot 1\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 $
