x^2-23/12 x+10/12 =0

解

x^{2} - \frac{23}{12} x + \frac{10}{12} = 0

解

x = \frac{5}{4}, x = \frac{2}{3}

+1

十進法表記

x = 1.25, x = 0.66666 \dots

解答ステップ

x^{2} - \frac{23}{12} x + \frac{10}{12} = 0

以下で両辺を乗じる:

12

12 x^{2} - 23 x + 10 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 23 ) \pm ( - 23 ) ^{2} - 4 \cdot 12 \cdot 10}{2 \cdot 12}

(- 23)^{2} - 4 \cdot 12 \cdot 10 = 7

x_{1, 2} = \frac{- ( - 23 ) \pm 7}{2 \cdot 12}

解を分離する

x_{1} = \frac{- ( - 23 ) + 7}{2 \cdot 12}, x_{2} = \frac{- ( - 23 ) - 7}{2 \cdot 12}

x = \frac{- ( - 23 ) + 7}{2 \cdot 12} : \frac{5}{4}

x = \frac{- ( - 23 ) - 7}{2 \cdot 12} : \frac{2}{3}

二次equationの解:

x = \frac{5}{4}, x = \frac{2}{3}
