erweitern (x+(1/x))*(x-(1/x))

Lösung

erweitern

(x + (\frac{1}{x})) \cdot (x - (\frac{1}{x}))

x^{2} - \frac{1}{x ^{2}}

Schritte zur Lösung

(x + (\frac{1}{x})) (x - (\frac{1}{x}))

Vereinfache

(x + (\frac{1}{x})) (x - (\frac{1}{x})) : (x + \frac{1}{x}) (x - \frac{1}{x})

= (x + \frac{1}{x}) (x - \frac{1}{x})

Apply Difference of Two Squares

(x + \frac{1}{x}) (x - \frac{1}{x}) : x^{2} - \frac{1}{x ^{2}}

= x^{2} - \frac{1}{x ^{2}}
