3+x-3x^2=9

解

3 + x - 3 x^{2} = 9

解

x = \frac{1}{6} - i \frac{71}{6}, x = \frac{1}{6} + i \frac{71}{6}

解答ステップ

3 + x - 3 x^{2} = 9

9

- 3 x^{2} + x - 6 = 0

解くとthe二次式

x_{1, 2} = \frac{- 1 \pm 1 ^{2} - 4 ( - 3 ) ( - 6 )}{2 ( - 3 )}

簡素化

1^{2} - 4 (- 3) (- 6) : 71 i

x_{1, 2} = \frac{- 1 \pm 71 i}{2 ( - 3 )}

解を分離する

x_{1} = \frac{- 1 + 71 i}{2 ( - 3 )}, x_{2} = \frac{- 1 - 71 i}{2 ( - 3 )}

x = \frac{- 1 + 71 i}{2 ( - 3 )} : \frac{1}{6} - i \frac{71}{6}

x = \frac{- 1 - 71 i}{2 ( - 3 )} : \frac{1}{6} + i \frac{71}{6}

二次equationの解:

x = \frac{1}{6} - i \frac{71}{6}, x = \frac{1}{6} + i \frac{71}{6}
