-x^2-11/3 x+2=0

解

- x^{2} - \frac{11}{3} x + 2 = 0

解

x = - \frac{11 + 193}{6}, x = \frac{193 - 11}{6}

+1

十進法表記

x = - 4.14874 \dots, x = 0.48207 \dots

解答ステップ

- x^{2} - \frac{11}{3} x + 2 = 0

以下で両辺を乗じる:

3

- 3 x^{2} - 11 x + 6 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 11 ) \pm ( - 11 ) ^{2} - 4 ( - 3 ) \cdot 6}{2 ( - 3 )}

(- 11)^{2} - 4 (- 3) \cdot 6 = 193

x_{1, 2} = \frac{- ( - 11 ) \pm 193}{2 ( - 3 )}

解を分離する

x_{1} = \frac{- ( - 11 ) + 193}{2 ( - 3 )}, x_{2} = \frac{- ( - 11 ) - 193}{2 ( - 3 )}

x = \frac{- ( - 11 ) + 193}{2 ( - 3 )} : - \frac{11 + 193}{6}

x = \frac{- ( - 11 ) - 193}{2 ( - 3 )} : \frac{193 - 11}{6}

二次equationの解:

x = - \frac{11 + 193}{6}, x = \frac{193 - 11}{6}
