2x^2-10x+3=0

解

2 x^{2} - 10 x + 3 = 0

解

x = \frac{5 + 19}{2}, x = \frac{5 - 19}{2}

+1

十進法表記

x = 4.67944 \dots, x = 0.32055 \dots

解答ステップ

2 x^{2} - 10 x + 3 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 10 ) \pm ( - 10 ) ^{2} - 4 \cdot 2 \cdot 3}{2 \cdot 2}

(- 10)^{2} - 4 \cdot 2 \cdot 3 = 219

x_{1, 2} = \frac{- ( - 10 ) \pm 2 19}{2 \cdot 2}

解を分離する

x_{1} = \frac{- ( - 10 ) + 2 19}{2 \cdot 2}, x_{2} = \frac{- ( - 10 ) - 2 19}{2 \cdot 2}

x = \frac{- ( - 10 ) + 2 19}{2 \cdot 2} : \frac{5 + 19}{2}

x = \frac{- ( - 10 ) - 2 19}{2 \cdot 2} : \frac{5 - 19}{2}

二次equationの解:

x = \frac{5 + 19}{2}, x = \frac{5 - 19}{2}
