erweitern ((x-3)(x-5)(x-6))*2

Lösung

erweitern

((x - 3) (x - 5) (x - 6)) \cdot 2

2 x^{3} - 28 x^{2} + 126 x - 180

Schritte zur Lösung

((x - 3) (x - 5) (x - 6)) \cdot 2

Entferne die Klammern:

(a) = a

= (x - 3) (x - 5) (x - 6) \cdot 2

= 2 (x - 3) (x - 5) (x - 6)

Multipliziere aus

(x - 3) (x - 5) : x^{2} - 8 x + 15

= 2 (x^{2} - 8 x + 15) (x - 6)

(x^{2} - 8 x + 15) (x - 6) : x^{3} - 14 x^{2} + 63 x - 90

= 2 (x^{3} - 14 x^{2} + 63 x - 90)

2 (x^{3} - 14 x^{2} + 63 x - 90) : 2 x^{3} - 28 x^{2} + 126 x - 180

= 2 x^{3} - 28 x^{2} + 126 x - 180

e x p an d (1 + i^{^{'}})^{12}
