-60x^2-60x=0

解

- 60 x^{2} - 60 x = 0

x = - 1, x = 0

解答ステップ

- 60 x^{2} - 60 x = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 60 ) \pm ( - 60 ) ^{2} - 4 ( - 60 ) \cdot 0}{2 ( - 60 )}

(- 60)^{2} - 4 (- 60) \cdot 0 = 60

x_{1, 2} = \frac{- ( - 60 ) \pm 60}{2 ( - 60 )}

解を分離する

x_{1} = \frac{- ( - 60 ) + 60}{2 ( - 60 )}, x_{2} = \frac{- ( - 60 ) - 60}{2 ( - 60 )}

x = \frac{- ( - 60 ) + 60}{2 ( - 60 )} : - 1

x = \frac{- ( - 60 ) - 60}{2 ( - 60 )} : 0

二次equationの解:

x = - 1, x = 0
