-7000x^2-7280x=144551

解

- 7000 x^{2} - 7280 x = 144551

解

x = - \frac{13}{25} - i \frac{3994429600}{14000}, x = - \frac{13}{25} + i \frac{3994429600}{14000}

解答ステップ

- 7000 x^{2} - 7280 x = 144551

144551

を左側に移動します

- 7000 x^{2} - 7280 x - 144551 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 7280 ) \pm ( - 7280 ) ^{2} - 4 ( - 7000 ) ( - 144551 )}{2 ( - 7000 )}

簡素化

(- 7280)^{2} - 4 (- 7000) (- 144551) : 3994429600 i

x_{1, 2} = \frac{- ( - 7280 ) \pm 3994429600 i}{2 ( - 7000 )}

解を分離する

x_{1} = \frac{- ( - 7280 ) + 3994429600 i}{2 ( - 7000 )}, x_{2} = \frac{- ( - 7280 ) - 3994429600 i}{2 ( - 7000 )}

x = \frac{- ( - 7280 ) + 3994429600 i}{2 ( - 7000 )} : - \frac{13}{25} - i \frac{3994429600}{14000}

x = \frac{- ( - 7280 ) - 3994429600 i}{2 ( - 7000 )} : - \frac{13}{25} + i \frac{3994429600}{14000}

二次equationの解:

x = - \frac{13}{25} - i \frac{3994429600}{14000}, x = - \frac{13}{25} + i \frac{3994429600}{14000}
