-x^2+11x-10=0

解

- x^{2} + 11 x - 10 = 0

x = 1, x = 10

解答ステップ

- x^{2} + 11 x - 10 = 0

解くとthe二次式

x_{1, 2} = \frac{- 11 \pm 1 1 ^{2} - 4 ( - 1 ) ( - 10 )}{2 ( - 1 )}

1 1^{2} - 4 (- 1) (- 10) = 9

x_{1, 2} = \frac{- 11 \pm 9}{2 ( - 1 )}

解を分離する

x_{1} = \frac{- 11 + 9}{2 ( - 1 )}, x_{2} = \frac{- 11 - 9}{2 ( - 1 )}

x = \frac{- 11 + 9}{2 ( - 1 )} : 1

x = \frac{- 11 - 9}{2 ( - 1 )} : 10

二次equationの解:

x = 1, x = 10
