-3x^2-26x=0

解

- 3 x^{2} - 26 x = 0

解

x = - \frac{26}{3}, x = 0

+1

十進法表記

x = - 8.66666 \dots, x = 0

解答ステップ

- 3 x^{2} - 26 x = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 26 ) \pm ( - 26 ) ^{2} - 4 ( - 3 ) \cdot 0}{2 ( - 3 )}

(- 26)^{2} - 4 (- 3) \cdot 0 = 26

x_{1, 2} = \frac{- ( - 26 ) \pm 26}{2 ( - 3 )}

解を分離する

x_{1} = \frac{- ( - 26 ) + 26}{2 ( - 3 )}, x_{2} = \frac{- ( - 26 ) - 26}{2 ( - 3 )}

x = \frac{- ( - 26 ) + 26}{2 ( - 3 )} : - \frac{26}{3}

x = \frac{- ( - 26 ) - 26}{2 ( - 3 )} : 0

二次equationの解:

x = - \frac{26}{3}, x = 0
