24x^2-48x+16=0

解

24 x^{2} - 48 x + 16 = 0

解

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

+1

十進法表記

x = 1.57735 \dots, x = 0.42264 \dots

解答ステップ

24 x^{2} - 48 x + 16 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 48 ) \pm ( - 48 ) ^{2} - 4 \cdot 24 \cdot 16}{2 \cdot 24}

(- 48)^{2} - 4 \cdot 24 \cdot 16 = 163

x_{1, 2} = \frac{- ( - 48 ) \pm 16 3}{2 \cdot 24}

解を分離する

x_{1} = \frac{- ( - 48 ) + 16 3}{2 \cdot 24}, x_{2} = \frac{- ( - 48 ) - 16 3}{2 \cdot 24}

x = \frac{- ( - 48 ) + 16 3}{2 \cdot 24} : \frac{3 + 3}{3}

x = \frac{- ( - 48 ) - 16 3}{2 \cdot 24} : \frac{3 - 3}{3}

二次equationの解:

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

121x^2-462x+441=360-72x

121 x^{2} - 462 x + 441 = 360 - 72 x

- 10 x^{2} + 180 = 0
