-3x^2-10x+24=0

解

- 3 x^{2} - 10 x + 24 = 0

解

x = - \frac{5 + 97}{3}, x = \frac{97 - 5}{3}

+1

十進法表記

x = - 4.94961 \dots, x = 1.61628 \dots

解答ステップ

- 3 x^{2} - 10 x + 24 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 10 ) \pm ( - 10 ) ^{2} - 4 ( - 3 ) \cdot 24}{2 ( - 3 )}

(- 10)^{2} - 4 (- 3) \cdot 24 = 297

x_{1, 2} = \frac{- ( - 10 ) \pm 2 97}{2 ( - 3 )}

解を分離する

x_{1} = \frac{- ( - 10 ) + 2 97}{2 ( - 3 )}, x_{2} = \frac{- ( - 10 ) - 2 97}{2 ( - 3 )}

x = \frac{- ( - 10 ) + 2 97}{2 ( - 3 )} : - \frac{5 + 97}{3}

x = \frac{- ( - 10 ) - 2 97}{2 ( - 3 )} : \frac{97 - 5}{3}

二次equationの解:

x = - \frac{5 + 97}{3}, x = \frac{97 - 5}{3}
