0=0.111-(0.1+0.1)c-6.0510^{-4}c^2*25.4

解

0 = 0.1 \cdot 11 - (0.1 + 0.1) c - 6.05 \cdot 1 0^{- 4} c^{2} \cdot 25.4

解

c = - \frac{0.2 + 0.1076148}{0.030734}, c = \frac{0.1076148 - 0.2}{0.030734}

十進法表記

c = - 17.18119 \dots, c = 4.16629 \dots

解答ステップ

0 = 0.1 \cdot 11 - (0.1 + 0.1) c - 6.05 \cdot 1 0^{- 4} c^{2} \cdot 25.4

拡張

0.1 \cdot 11 - (0.1 + 0.1) c - 6.05 \cdot 1 0^{- 4} c^{2} \cdot 25.4 : 1.1 - 0.2 c - 0.015367 c^{2}

0 = 1.1 - 0.2 c - 0.015367 c^{2}

辺を交換する

1.1 - 0.2 c - 0.015367 c^{2} = 0

標準的な形式で書く

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

- 0.015367 c^{2} - 0.2 c + 1.1 = 0

解くとthe二次式

c_{1, 2} = \frac{- ( - 0.2 ) \pm ( - 0.2 ) ^{2} - 4 ( - 0.015367 ) \cdot 1.1}{2 ( - 0.015367 )}

(- 0.2)^{2} - 4 (- 0.015367) \cdot 1.1 = 0.1076148

c_{1, 2} = \frac{- ( - 0.2 ) \pm 0.1076148}{2 ( - 0.015367 )}

解を分離する

c_{1} = \frac{- ( - 0.2 ) + 0.1076148}{2 ( - 0.015367 )}, c_{2} = \frac{- ( - 0.2 ) - 0.1076148}{2 ( - 0.015367 )}

c = \frac{- ( - 0.2 ) + 0.1076148}{2 ( - 0.015367 )} : - \frac{0.2 + 0.1076148}{0.030734}

c = \frac{- ( - 0.2 ) - 0.1076148}{2 ( - 0.015367 )} : \frac{0.1076148 - 0.2}{0.030734}

二次equationの解:

c = - \frac{0.2 + 0.1076148}{0.030734}, c = \frac{0.1076148 - 0.2}{0.030734}
