-6x^2-10x=0

解

- 6 x^{2} - 10 x = 0

解

x = - \frac{5}{3}, x = 0

+1

十進法表記

x = - 1.66666 \dots, x = 0

解答ステップ

- 6 x^{2} - 10 x = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 10 ) \pm ( - 10 ) ^{2} - 4 ( - 6 ) \cdot 0}{2 ( - 6 )}

(- 10)^{2} - 4 (- 6) \cdot 0 = 10

x_{1, 2} = \frac{- ( - 10 ) \pm 10}{2 ( - 6 )}

解を分離する

x_{1} = \frac{- ( - 10 ) + 10}{2 ( - 6 )}, x_{2} = \frac{- ( - 10 ) - 10}{2 ( - 6 )}

x = \frac{- ( - 10 ) + 10}{2 ( - 6 )} : - \frac{5}{3}

x = \frac{- ( - 10 ) - 10}{2 ( - 6 )} : 0

二次equationの解:

x = - \frac{5}{3}, x = 0
