2=-35(2x/(-0.00796)-(x/(-0.00796))^2)

解

2 = - 35 \cdot (2 \cdot \frac{x}{- 0.00796} - (\frac{x}{- 0.00796})^{2})

解

x = \frac{- 0.004435312 + 0.2786 \frac{\frac{9.19888 E - 9}{0.07761796} + \frac{1.88676 E - 9}{0.2786}}{0.00046 \dots}}{0.5572}, x = \frac{- 0.004435312 - 0.2786 \frac{\frac{9.19888 E - 9}{0.07761796} + \frac{1.88676 E - 9}{0.2786}}{0.00046 \dots}}{0.5572}

十進法表記

x = 0.00022 \dots, x = - 0.01614 \dots

解答ステップ

2 = - 35 (2 \cdot \frac{x}{- 0.00796} - (\frac{x}{- 0.00796})^{2})

拡張

- 35 (2 \cdot \frac{x}{- 0.00796} - (\frac{x}{- 0.00796})^{2}) : \frac{70 x}{0.00796} + \frac{35 x ^{2}}{0.0000633616}

2 = \frac{70 x}{0.00796} + \frac{35 x ^{2}}{0.0000633616}

辺を交換する

\frac{70 x}{0.00796} + \frac{35 x ^{2}}{0.0000633616} = 2

を左側に移動します

\frac{70 x}{0.00796} + \frac{35 x ^{2}}{0.0000633616} - 2 = 0

以下で両辺を割る

552385.04078 \dots

\frac{\frac{70 x}{0.00796}}{552385.04078 \dots} + \frac{\frac{35 x ^{2}}{0.0000633616}}{552385.04078 \dots} - \frac{2}{552385.04078 \dots} = \frac{0}{552385.04078 \dots}

標準的な形式で書く

a x^{2} + b x + c = 0

x^{2} + \frac{0.004435312 x}{0.2786} - \frac{1.00872 E - 6}{0.2786} = 0

解くとthe二次式

x_{1, 2} = \frac{- \frac{0.004435312}{0.2786} \pm ( \frac{0.004435312}{0.2786} ) ^{2} - 4 \cdot 1 \cdot ( - \frac{1.00872 E - 6}{0.2786} )}{2 \cdot 1}

(\frac{0.004435312}{0.2786})^{2} - 4 \cdot 1 \cdot (- \frac{1.00872 E - 6}{0.2786}) = \frac{\frac{9.19888 E - 9}{0.07761796} + \frac{1.88676 E - 9}{0.2786}}{0.00046 \dots}

x_{1, 2} = \frac{- \frac{0.004435312}{0.2786} \pm \frac{\frac{9.19888 E - 9}{0.07761796} + \frac{1.88676 E - 9}{0.2786}}{0.00046 \dots}}{2 \cdot 1}

解を分離する

x_{1} = \frac{- \frac{0.004435312}{0.2786} + \frac{\frac{9.19888 E - 9}{0.07761796} + \frac{1.88676 E - 9}{0.2786}}{0.00046 \dots}}{2 \cdot 1}, x_{2} = \frac{- \frac{0.004435312}{0.2786} - \frac{\frac{9.19888 E - 9}{0.07761796} + \frac{1.88676 E - 9}{0.2786}}{0.00046 \dots}}{2 \cdot 1}

x = \frac{- \frac{0.004435312}{0.2786} + \frac{\frac{9.19888 E - 9}{0.07761796} + \frac{1.88676 E - 9}{0.2786}}{0.00046 \dots}}{2 \cdot 1} : \frac{- 0.004435312 + 0.2786 \frac{\frac{9.19888 E - 9}{0.07761796} + \frac{1.88676 E - 9}{0.2786}}{0.00046 \dots}}{0.5572}

x = \frac{- \frac{0.004435312}{0.2786} - \frac{\frac{9.19888 E - 9}{0.07761796} + \frac{1.88676 E - 9}{0.2786}}{0.00046 \dots}}{2 \cdot 1} : \frac{- 0.004435312 - 0.2786 \frac{\frac{9.19888 E - 9}{0.07761796} + \frac{1.88676 E - 9}{0.2786}}{0.00046 \dots}}{0.5572}

二次equationの解:

x = \frac{- 0.004435312 + 0.2786 \frac{\frac{9.19888 E - 9}{0.07761796} + \frac{1.88676 E - 9}{0.2786}}{0.00046 \dots}}{0.5572}, x = \frac{- 0.004435312 - 0.2786 \frac{\frac{9.19888 E - 9}{0.07761796} + \frac{1.88676 E - 9}{0.2786}}{0.00046 \dots}}{0.5572}
