-6x^2-24x+564=0

解

- 6 x^{2} - 24 x + 564 = 0

解

x = - 2 - 72, x = 72 - 2

+1

十進法表記

x = - 11.89949 \dots, x = 7.89949 \dots

解答ステップ

- 6 x^{2} - 24 x + 564 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 24 ) \pm ( - 24 ) ^{2} - 4 ( - 6 ) \cdot 564}{2 ( - 6 )}

(- 24)^{2} - 4 (- 6) \cdot 564 = 842

x_{1, 2} = \frac{- ( - 24 ) \pm 84 2}{2 ( - 6 )}

解を分離する

x_{1} = \frac{- ( - 24 ) + 84 2}{2 ( - 6 )}, x_{2} = \frac{- ( - 24 ) - 84 2}{2 ( - 6 )}

x = \frac{- ( - 24 ) + 84 2}{2 ( - 6 )} : - 2 - 72

x = \frac{- ( - 24 ) - 84 2}{2 ( - 6 )} : 72 - 2

二次equationの解:

x = - 2 - 72, x = 72 - 2
