逆 (2x^2-1)(-x^2-6)

解

逆

(2 x^{2} - 1) (- x^{2} - 6)

- \frac{11 + - 8 x + 169}{4}, - - \frac{11 + - 8 x + 169}{4}, - \frac{11 - - 8 x + 169}{4}, - - \frac{11 - - 8 x + 169}{4}

解答ステップ

y = (2 x^{2} - 1) (- x^{2} - 6)

x

を以下で置き換える:

y

x = (2 y^{2} - 1) (- y^{2} - 6)

y

を解く

x = (2 y^{2} - 1) (- y^{2} - 6)

- \frac{11 + - 8 x + 169}{4}, - - \frac{11 + - 8 x + 169}{4}, - \frac{11 - - 8 x + 169}{4}, - - \frac{11 - - 8 x + 169}{4}
