3902850x^2-6615000x+984760=0

解

3902850 x^{2} - 6615000 x + 984760 = 0

解

x = \frac{2 ( 75 105 + 383122 )}{177 105}, x = \frac{2 ( 75 105 - 383122 )}{177 105}

+1

十進法表記

x = 1.53000 \dots, x = 0.16491 \dots

解答ステップ

3902850 x^{2} - 6615000 x + 984760 = 0

以下で両辺を割る

3902850

\frac{3902850 x ^{2}}{3902850} - \frac{6615000 x}{3902850} + \frac{984760}{3902850} = \frac{0}{3902850}

標準的な形式で書く

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

x^{2} - \frac{100 x}{59} + \frac{14068}{55755} = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - \frac{100}{59} ) \pm ( - \frac{100}{59} ) ^{2} - 4 \cdot 1 \cdot \frac{14068}{55755}}{2 \cdot 1}

(- \frac{100}{59})^{2} - 4 \cdot 1 \cdot \frac{14068}{55755} = \frac{4 383122}{177 105}

x_{1, 2} = \frac{- ( - \frac{100}{59} ) \pm \frac{4 383122}{177 105}}{2 \cdot 1}

解を分離する

x_{1} = \frac{- ( - \frac{100}{59} ) + \frac{4 383122}{177 105}}{2 \cdot 1}, x_{2} = \frac{- ( - \frac{100}{59} ) - \frac{4 383122}{177 105}}{2 \cdot 1}

x = \frac{- ( - \frac{100}{59} ) + \frac{4 383122}{177 105}}{2 \cdot 1} : \frac{2 ( 75 105 + 383122 )}{177 105}

x = \frac{- ( - \frac{100}{59} ) - \frac{4 383122}{177 105}}{2 \cdot 1} : \frac{2 ( 75 105 - 383122 )}{177 105}

二次equationの解:

x = \frac{2 ( 75 105 + 383122 )}{177 105}, x = \frac{2 ( 75 105 - 383122 )}{177 105}
