-2.092x^2+80x=0

解

- 2.092 x^{2} + 80 x = 0

解

x = 0, x = \frac{20000}{523}

+1

十進法表記

x = 0, x = 38.24091 \dots

解答ステップ

- 2.092 x^{2} + 80 x = 0

以下で両辺を乗じる:

1000

- 2092 x^{2} + 80000 x = 0

解くとthe二次式

x_{1, 2} = \frac{- 80000 \pm 8000 0 ^{2} - 4 ( - 2092 ) \cdot 0}{2 ( - 2092 )}

8000 0^{2} - 4 (- 2092) \cdot 0 = 80000

x_{1, 2} = \frac{- 80000 \pm 80000}{2 ( - 2092 )}

解を分離する

x_{1} = \frac{- 80000 + 80000}{2 ( - 2092 )}, x_{2} = \frac{- 80000 - 80000}{2 ( - 2092 )}

x = \frac{- 80000 + 80000}{2 ( - 2092 )} : 0

x = \frac{- 80000 - 80000}{2 ( - 2092 )} : \frac{20000}{523}

二次equationの解:

x = 0, x = \frac{20000}{523}
