-3x^2-4x+6=0

解

- 3 x^{2} - 4 x + 6 = 0

解

x = - \frac{2 + 22}{3}, x = \frac{22 - 2}{3}

+1

十進法表記

x = - 2.23013 \dots, x = 0.89680 \dots

解答ステップ

- 3 x^{2} - 4 x + 6 = 0

解くとthe二次式

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

(- 4)^{2} - 4 (- 3) \cdot 6 = 222

x_{1, 2} = \frac{- ( - 4 ) \pm 2 22}{2 ( - 3 )}

解を分離する

x_{1} = \frac{- ( - 4 ) + 2 22}{2 ( - 3 )}, x_{2} = \frac{- ( - 4 ) - 2 22}{2 ( - 3 )}

x = \frac{- ( - 4 ) + 2 22}{2 ( - 3 )} : - \frac{2 + 22}{3}

x = \frac{- ( - 4 ) - 2 22}{2 ( - 3 )} : \frac{22 - 2}{3}

二次equationの解:

x = - \frac{2 + 22}{3}, x = \frac{22 - 2}{3}
