-11=0.039x^2-0.9675x

解

- 11 = 0.039 x^{2} - 0.9675 x

解

x = \frac{0.9675}{0.078} + i \frac{0.77994375}{0.078}, x = \frac{0.9675}{0.078} - i \frac{0.77994375}{0.078}

解答ステップ

- 11 = 0.039 x^{2} - 0.9675 x

辺を交換する

0.039 x^{2} - 0.9675 x = - 11

11

を左側に移動します

0.039 x^{2} - 0.9675 x + 11 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 0.9675 ) \pm ( - 0.9675 ) ^{2} - 4 \cdot 0.039 \cdot 11}{2 \cdot 0.039}

簡素化

(- 0.9675)^{2} - 4 \cdot 0.039 \cdot 11 : 0.77994375 i

x_{1, 2} = \frac{- ( - 0.9675 ) \pm 0.77994375 i}{2 \cdot 0.039}

解を分離する

x_{1} = \frac{- ( - 0.9675 ) + 0.77994375 i}{2 \cdot 0.039}, x_{2} = \frac{- ( - 0.9675 ) - 0.77994375 i}{2 \cdot 0.039}

x = \frac{- ( - 0.9675 ) + 0.77994375 i}{2 \cdot 0.039} : \frac{0.9675}{0.078} + i \frac{0.77994375}{0.078}

x = \frac{- ( - 0.9675 ) - 0.77994375 i}{2 \cdot 0.039} : \frac{0.9675}{0.078} - i \frac{0.77994375}{0.078}

二次equationの解:

x = \frac{0.9675}{0.078} + i \frac{0.77994375}{0.078}, x = \frac{0.9675}{0.078} - i \frac{0.77994375}{0.078}
