19x^2-119x+60=0

解

19 x^{2} - 119 x + 60 = 0

解

x = \frac{119 + 9601}{38}, x = \frac{119 - 9601}{38}

+1

十進法表記

x = 5.71012 \dots, x = 0.55303 \dots

解答ステップ

19 x^{2} - 119 x + 60 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 119 ) \pm ( - 119 ) ^{2} - 4 \cdot 19 \cdot 60}{2 \cdot 19}

(- 119)^{2} - 4 \cdot 19 \cdot 60 = 9601

x_{1, 2} = \frac{- ( - 119 ) \pm 9601}{2 \cdot 19}

解を分離する

x_{1} = \frac{- ( - 119 ) + 9601}{2 \cdot 19}, x_{2} = \frac{- ( - 119 ) - 9601}{2 \cdot 19}

x = \frac{- ( - 119 ) + 9601}{2 \cdot 19} : \frac{119 + 9601}{38}

x = \frac{- ( - 119 ) - 9601}{2 \cdot 19} : \frac{119 - 9601}{38}

二次equationの解:

x = \frac{119 + 9601}{38}, x = \frac{119 - 9601}{38}
