Schritte zur Lösung

(x^{2} + 4 x - 2)^{9}

(x^{2} + 4 x - 2)^{9} = (x^{2} + 4 x - 2) (x^{2} + 4 x - 2) (x^{2} + 4 x - 2) (x^{2} + 4 x - 2) (x^{2} + 4 x - 2) (x^{2} + 4 x - 2) (x^{2} + 4 x - 2) (x^{2} + 4 x - 2) (x^{2} + 4 x - 2)

= (x^{2} + 4 x - 2) (x^{2} + 4 x - 2) (x^{2} + 4 x - 2) (x^{2} + 4 x - 2) (x^{2} + 4 x - 2) (x^{2} + 4 x - 2) (x^{2} + 4 x - 2) (x^{2} + 4 x - 2) (x^{2} + 4 x - 2)
