-3x^2-24x-13=-13

解

- 3 x^{2} - 24 x - 13 = - 13

x = - 8, x = 0

解答ステップ

- 3 x^{2} - 24 x - 13 = - 13

13

- 3 x^{2} - 24 x = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 24 ) \pm ( - 24 ) ^{2} - 4 ( - 3 ) \cdot 0}{2 ( - 3 )}

(- 24)^{2} - 4 (- 3) \cdot 0 = 24

x_{1, 2} = \frac{- ( - 24 ) \pm 24}{2 ( - 3 )}

解を分離する

x_{1} = \frac{- ( - 24 ) + 24}{2 ( - 3 )}, x_{2} = \frac{- ( - 24 ) - 24}{2 ( - 3 )}

x = \frac{- ( - 24 ) + 24}{2 ( - 3 )} : - 8

x = \frac{- ( - 24 ) - 24}{2 ( - 3 )} : 0

二次equationの解:

x = - 8, x = 0
