0=-26.47x^2+62.557x+332.16

解

0 = - 26.47 x^{2} + 62.557 x + 332.16

解

x = - \frac{- 62557 + 6255 7 ^{2} + 35169100800}{52940}, x = \frac{6255 7 ^{2} + 35169100800 + 62557}{52940}

+1

十進法表記

x = - 2.55262 \dots, x = 4.91594 \dots

解答ステップ

0 = - 26.47 x^{2} + 62.557 x + 332.16

以下で両辺を乗じる:

1000

0 = - 26470 x^{2} + 62557 x + 332160

辺を交換する

- 26470 x^{2} + 62557 x + 332160 = 0

解くとthe二次式

x_{1, 2} = \frac{- 62557 \pm 6255 7 ^{2} - 4 ( - 26470 ) \cdot 332160}{2 ( - 26470 )}

6255 7^{2} - 4 (- 26470) \cdot 332160 = 6255 7^{2} + 35169100800

x_{1, 2} = \frac{- 62557 \pm 6255 7 ^{2} + 35169100800}{2 ( - 26470 )}

解を分離する

x_{1} = \frac{- 62557 + 6255 7 ^{2} + 35169100800}{2 ( - 26470 )}, x_{2} = \frac{- 62557 - 6255 7 ^{2} + 35169100800}{2 ( - 26470 )}

x = \frac{- 62557 + 6255 7 ^{2} + 35169100800}{2 ( - 26470 )} : - \frac{- 62557 + 6255 7 ^{2} + 35169100800}{52940}

x = \frac{- 62557 - 6255 7 ^{2} + 35169100800}{2 ( - 26470 )} : \frac{6255 7 ^{2} + 35169100800 + 62557}{52940}

二次equationの解:

x = - \frac{- 62557 + 6255 7 ^{2} + 35169100800}{52940}, x = \frac{6255 7 ^{2} + 35169100800 + 62557}{52940}
