-16x^2+266x+102=0

解

- 16 x^{2} + 266 x + 102 = 0

x = - \frac{3}{8}, x = 17

十進法表記

x = - 0.375, x = 17

解答ステップ

- 16 x^{2} + 266 x + 102 = 0

解くとthe二次式

x_{1, 2} = \frac{- 266 \pm 26 6 ^{2} - 4 ( - 16 ) \cdot 102}{2 ( - 16 )}

26 6^{2} - 4 (- 16) \cdot 102 = 278

x_{1, 2} = \frac{- 266 \pm 278}{2 ( - 16 )}

解を分離する

x_{1} = \frac{- 266 + 278}{2 ( - 16 )}, x_{2} = \frac{- 266 - 278}{2 ( - 16 )}

x = \frac{- 266 + 278}{2 ( - 16 )} : - \frac{3}{8}

x = \frac{- 266 - 278}{2 ( - 16 )} : 17

二次equationの解:

x = - \frac{3}{8}, x = 17
