解答ステップ

(1 + 3 x^{2} - 2 x^{4})^{6}

(1 + 3 x^{2} - 2 x^{4})^{6} = (1 + 3 x^{2} - 2 x^{4}) (1 + 3 x^{2} - 2 x^{4}) (1 + 3 x^{2} - 2 x^{4}) (1 + 3 x^{2} - 2 x^{4}) (1 + 3 x^{2} - 2 x^{4}) (1 + 3 x^{2} - 2 x^{4})

= (- 2 x^{4} + 3 x^{2} + 1) (- 2 x^{4} + 3 x^{2} + 1) (- 2 x^{4} + 3 x^{2} + 1) (- 2 x^{4} + 3 x^{2} + 1) (- 2 x^{4} + 3 x^{2} + 1) (- 2 x^{4} + 3 x^{2} + 1)
