24x^2-10x-3=0

解

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

解

x = \frac{5 + 97}{24}, x = \frac{5 - 97}{24}

+1

十進法表記

x = 0.61870 \dots, x = - 0.20203 \dots

解答ステップ

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

解くとthe二次式

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

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

x_{1, 2} = \frac{- ( - 10 ) \pm 2 97}{2 \cdot 24}

解を分離する

x_{1} = \frac{- ( - 10 ) + 2 97}{2 \cdot 24}, x_{2} = \frac{- ( - 10 ) - 2 97}{2 \cdot 24}

x = \frac{- ( - 10 ) + 2 97}{2 \cdot 24} : \frac{5 + 97}{24}

x = \frac{- ( - 10 ) - 2 97}{2 \cdot 24} : \frac{5 - 97}{24}

二次equationの解:

x = \frac{5 + 97}{24}, x = \frac{5 - 97}{24}
