-x^2-10x+25=0

解

- x^{2} - 10 x + 25 = 0

解

x = - 5 (1 + 2), x = 5 (2 - 1)

+1

十進法表記

x = - 12.07106 \dots, x = 2.07106 \dots

解答ステップ

- x^{2} - 10 x + 25 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 10 ) \pm ( - 10 ) ^{2} - 4 ( - 1 ) \cdot 25}{2 ( - 1 )}

(- 10)^{2} - 4 (- 1) \cdot 25 = 102

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

解を分離する

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

x = \frac{- ( - 10 ) + 10 2}{2 ( - 1 )} : - 5 (1 + 2)

x = \frac{- ( - 10 ) - 10 2}{2 ( - 1 )} : 5 (2 - 1)

二次equationの解:

x = - 5 (1 + 2), x = 5 (2 - 1)
