0=2000x^2+1000.01x-23/5860

解

0 = 2000 x^{2} + 1000.01 x - \frac{23}{5860}

解

x = \frac{- 100001 + 200000 \frac{10000 1 ^{2}}{20000 0 ^{2}} + \frac{23}{2930000}}{400000}, x = \frac{- 100001 - 200000 \frac{10000 1 ^{2}}{20000 0 ^{2}} + \frac{23}{2930000}}{400000}

十進法表記

x = 3.92484 E - 6, x = - 0.50000 \dots

解答ステップ

0 = 2000 x^{2} + 1000.01 x - \frac{23}{5860}

以下で両辺を乗じる:

100

0 = 200000 x^{2} + 100001 x - \frac{115}{293}

以下で両辺を乗じる:

293

0 = 58600000 x^{2} + 29300293 x - 115

辺を交換する

58600000 x^{2} + 29300293 x - 115 = 0

以下で両辺を割る

58600000

\frac{58600000 x ^{2}}{58600000} + \frac{29300293 x}{58600000} - \frac{115}{58600000} = \frac{0}{58600000}

標準的な形式で書く

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

x^{2} + \frac{100001 x}{200000} - \frac{23}{11720000} = 0

解くとthe二次式

x_{1, 2} = \frac{- \frac{100001}{200000} \pm ( \frac{100001}{200000} ) ^{2} - 4 \cdot 1 \cdot ( - \frac{23}{11720000} )}{2 \cdot 1}

(\frac{100001}{200000})^{2} - 4 \cdot 1 \cdot (- \frac{23}{11720000}) = \frac{10000 1 ^{2}}{20000 0 ^{2}} + \frac{23}{2930000}

x_{1, 2} = \frac{- \frac{100001}{200000} \pm \frac{10000 1 ^{2}}{20000 0 ^{2}} + \frac{23}{2930000}}{2 \cdot 1}

解を分離する

x_{1} = \frac{- \frac{100001}{200000} + \frac{10000 1 ^{2}}{20000 0 ^{2}} + \frac{23}{2930000}}{2 \cdot 1}, x_{2} = \frac{- \frac{100001}{200000} - \frac{10000 1 ^{2}}{20000 0 ^{2}} + \frac{23}{2930000}}{2 \cdot 1}

x = \frac{- \frac{100001}{200000} + \frac{10000 1 ^{2}}{20000 0 ^{2}} + \frac{23}{2930000}}{2 \cdot 1} : \frac{- 100001 + 200000 \frac{10000 1 ^{2}}{20000 0 ^{2}} + \frac{23}{2930000}}{400000}

x = \frac{- \frac{100001}{200000} - \frac{10000 1 ^{2}}{20000 0 ^{2}} + \frac{23}{2930000}}{2 \cdot 1} : \frac{- 100001 - 200000 \frac{10000 1 ^{2}}{20000 0 ^{2}} + \frac{23}{2930000}}{400000}

二次equationの解:

x = \frac{- 100001 + 200000 \frac{10000 1 ^{2}}{20000 0 ^{2}} + \frac{23}{2930000}}{400000}, x = \frac{- 100001 - 200000 \frac{10000 1 ^{2}}{20000 0 ^{2}} + \frac{23}{2930000}}{400000}
