2+x-6x^2=0

解

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

解

x = - \frac{1}{2}, x = \frac{2}{3}

+1

十進法表記

x = - 0.5, x = 0.66666 \dots

解答ステップ

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

標準的な形式で書く

a x^{2} + b x + c = 0

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

解くとthe二次式

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

1^{2} - 4 (- 6) \cdot 2 = 7

x_{1, 2} = \frac{- 1 \pm 7}{2 ( - 6 )}

解を分離する

x_{1} = \frac{- 1 + 7}{2 ( - 6 )}, x_{2} = \frac{- 1 - 7}{2 ( - 6 )}

x = \frac{- 1 + 7}{2 ( - 6 )} : - \frac{1}{2}

x = \frac{- 1 - 7}{2 ( - 6 )} : \frac{2}{3}

二次equationの解:

x = - \frac{1}{2}, x = \frac{2}{3}
