Lösung

erweitern

x^{2} - 1 (x^{2} - 1) - x^{2} + 1 (x^{2} + 1)

x^{2} x^{2} - 1 - x^{2} - 1 - x^{2} x^{2} + 1 - x^{2} + 1

Schritte zur Lösung

x^{2} - 1 (x^{2} - 1) - x^{2} + 1 (x^{2} + 1)

Schreibe

x^{2} - 1 (x^{2} - 1)

um:

x^{2} x^{2} - 1 - x^{2} - 1

= x^{2} x^{2} - 1 - x^{2} - 1 - x^{2} + 1 (x^{2} + 1)

Schreibe

- x^{2} + 1 (x^{2} + 1)

um:

- x^{2} x^{2} + 1 - x^{2} + 1

= x^{2} x^{2} - 1 - x^{2} - 1 - x^{2} x^{2} + 1 - x^{2} + 1
