18x^2-6x+2=0

解

18 x^{2} - 6 x + 2 = 0

解

x = \frac{1}{6} + i \frac{3}{6}, x = \frac{1}{6} - i \frac{3}{6}

解答ステップ

18 x^{2} - 6 x + 2 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 6 ) \pm ( - 6 ) ^{2} - 4 \cdot 18 \cdot 2}{2 \cdot 18}

簡素化

(- 6)^{2} - 4 \cdot 18 \cdot 2 : 63 i

x_{1, 2} = \frac{- ( - 6 ) \pm 6 3 i}{2 \cdot 18}

解を分離する

x_{1} = \frac{- ( - 6 ) + 6 3 i}{2 \cdot 18}, x_{2} = \frac{- ( - 6 ) - 6 3 i}{2 \cdot 18}

x = \frac{- ( - 6 ) + 6 3 i}{2 \cdot 18} : \frac{1}{6} + i \frac{3}{6}

x = \frac{- ( - 6 ) - 6 3 i}{2 \cdot 18} : \frac{1}{6} - i \frac{3}{6}

二次equationの解:

x = \frac{1}{6} + i \frac{3}{6}, x = \frac{1}{6} - i \frac{3}{6}
