-0.0241x^2+x+5.5=0

解

- 0.0241 x^{2} + x + 5.5 = 0

x = - \frac{- 1 + 1.5302}{0.0482}, x = \frac{1 + 1.5302}{0.0482}

十進法表記

x = - 4.91727 \dots, x = 46.41104 \dots

解答ステップ

- 0.0241 x^{2} + x + 5.5 = 0

解くとthe二次式

x_{1, 2} = \frac{- 1 \pm 1 ^{2} - 4 ( - 0.0241 ) \cdot 5.5}{2 ( - 0.0241 )}

1^{2} - 4 (- 0.0241) \cdot 5.5 = 1.5302

x_{1, 2} = \frac{- 1 \pm 1.5302}{2 ( - 0.0241 )}

解を分離する

x_{1} = \frac{- 1 + 1.5302}{2 ( - 0.0241 )}, x_{2} = \frac{- 1 - 1.5302}{2 ( - 0.0241 )}

x = \frac{- 1 + 1.5302}{2 ( - 0.0241 )} : - \frac{- 1 + 1.5302}{0.0482}

x = \frac{- 1 - 1.5302}{2 ( - 0.0241 )} : \frac{1 + 1.5302}{0.0482}

二次equationの解:

x = - \frac{- 1 + 1.5302}{0.0482}, x = \frac{1 + 1.5302}{0.0482}
