Beispiel Nr: 06
$(ax+ b)\cdot (ax - b) = a^{2}x^{2} - b^{2} \\ (a + b)\cdot (a - b)\\ \textbf{Gegeben:} \\ (1\frac{1}{3}x + 1\frac{1}{4})(1\frac{1}{3}x - 1\frac{1}{4})\\ \\ \textbf{Rechnung:} \\\text{3. Binomische Formel} \\(1\frac{1}{3}x+1\frac{1}{4})(1\frac{1}{3}x-1\frac{1}{4})=1\frac{1}{3}^{2}x^{2}-1\frac{1}{4}^{2} \\(1\frac{1}{3}x+1\frac{1}{4})(1\frac{1}{3} x-1\frac{1}{4})= 1\frac{7}{9}x^2-1\frac{9}{16} $
