-332.65=(0.0004)x^2-0.7281x

解

- 332.65 = (0.0004) x^{2} - 0.7281 x

解

x = \frac{0.7281}{0.0008} + i \frac{0.00211039}{0.0008}, x = \frac{0.7281}{0.0008} - i \frac{0.00211039}{0.0008}

解答ステップ

- 332.65 = (0.0004) x^{2} - 0.7281 x

改良

- 332.65 = 0.0004 x^{2} - 0.7281 x

辺を交換する

0.0004 x^{2} - 0.7281 x = - 332.65

を左側に移動します

0.0004 x^{2} - 0.7281 x + 332.65 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 0.7281 ) \pm ( - 0.7281 ) ^{2} - 4 \cdot 0.0004 \cdot 332.65}{2 \cdot 0.0004}

簡素化

(- 0.7281)^{2} - 4 \cdot 0.0004 \cdot 332.65 : 0.00211039 i

x_{1, 2} = \frac{- ( - 0.7281 ) \pm 0.00211039 i}{2 \cdot 0.0004}

解を分離する

x_{1} = \frac{- ( - 0.7281 ) + 0.00211039 i}{2 \cdot 0.0004}, x_{2} = \frac{- ( - 0.7281 ) - 0.00211039 i}{2 \cdot 0.0004}

x = \frac{- ( - 0.7281 ) + 0.00211039 i}{2 \cdot 0.0004} : \frac{0.7281}{0.0008} + i \frac{0.00211039}{0.0008}

x = \frac{- ( - 0.7281 ) - 0.00211039 i}{2 \cdot 0.0004} : \frac{0.7281}{0.0008} - i \frac{0.00211039}{0.0008}

二次equationの解:

x = \frac{0.7281}{0.0008} + i \frac{0.00211039}{0.0008}, x = \frac{0.7281}{0.0008} - i \frac{0.00211039}{0.0008}
