3x^2-24x+32=0

解

3 x^{2} - 24 x + 32 = 0

解

x = \frac{4 ( 3 + 3 )}{3}, x = \frac{4 ( 3 - 3 )}{3}

+1

十進法表記

x = 6.30940 \dots, x = 1.69059 \dots

解答ステップ

3 x^{2} - 24 x + 32 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 24 ) \pm ( - 24 ) ^{2} - 4 \cdot 3 \cdot 32}{2 \cdot 3}

(- 24)^{2} - 4 \cdot 3 \cdot 32 = 83

x_{1, 2} = \frac{- ( - 24 ) \pm 8 3}{2 \cdot 3}

解を分離する

x_{1} = \frac{- ( - 24 ) + 8 3}{2 \cdot 3}, x_{2} = \frac{- ( - 24 ) - 8 3}{2 \cdot 3}

x = \frac{- ( - 24 ) + 8 3}{2 \cdot 3} : \frac{4 ( 3 + 3 )}{3}

x = \frac{- ( - 24 ) - 8 3}{2 \cdot 3} : \frac{4 ( 3 - 3 )}{3}

二次equationの解:

x = \frac{4 ( 3 + 3 )}{3}, x = \frac{4 ( 3 - 3 )}{3}
