0.25=-0.00008x^2-0.0035x+1.0519

解

0.25 = - 0.00008 x^{2} - 0.0035 x + 1.0519

解

x = - \frac{0.0035 + 0.000268858}{0.00016}, x = \frac{0.000268858 - 0.0035}{0.00016}

+1

十進法表記

x = - 124.35556 \dots, x = 80.60556 \dots

解答ステップ

0.25 = - 0.00008 x^{2} - 0.0035 x + 1.0519

辺を交換する

- 0.00008 x^{2} - 0.0035 x + 1.0519 = 0.25

- 0.00008 x^{2} - 0.0035 x + 0.8019 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 0.0035 ) \pm ( - 0.0035 ) ^{2} - 4 ( - 0.00008 ) \cdot 0.8019}{2 ( - 0.00008 )}

(- 0.0035)^{2} - 4 (- 0.00008) \cdot 0.8019 = 0.000268858

x_{1, 2} = \frac{- ( - 0.0035 ) \pm 0.000268858}{2 ( - 0.00008 )}

解を分離する

x_{1} = \frac{- ( - 0.0035 ) + 0.000268858}{2 ( - 0.00008 )}, x_{2} = \frac{- ( - 0.0035 ) - 0.000268858}{2 ( - 0.00008 )}

x = \frac{- ( - 0.0035 ) + 0.000268858}{2 ( - 0.00008 )} : - \frac{0.0035 + 0.000268858}{0.00016}

x = \frac{- ( - 0.0035 ) - 0.000268858}{2 ( - 0.00008 )} : \frac{0.000268858 - 0.0035}{0.00016}

二次equationの解:

x = - \frac{0.0035 + 0.000268858}{0.00016}, x = \frac{0.000268858 - 0.0035}{0.00016}
