vereinfachen x^2-2(a+1/a)x+4

Lösung

vereinfachen

x^{2} - 2 (a + \frac{1}{a}) x + 4

x^{2} - \frac{2 x ( a ^{2} + 1 )}{a} + 4

Schritte zur Lösung

x^{2} - 2 (a + \frac{1}{a}) x + 4

Füge zusammen:

a + \frac{1}{a} : \frac{a ^{2} + 1}{a}

= x^{2} - 2 \cdot \frac{a ^{2} + 1}{a} x + 4

Vereinfache

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

= x^{2} - \frac{2 ( a ^{2} + 1 ) x}{a} + 4

= x^{2} - \frac{2 x ( a ^{2} + 1 )}{a} + 4
