29x^2-4x+1=0

解

29 x^{2} - 4 x + 1 = 0

解

x = \frac{2}{29} + i \frac{5}{29}, x = \frac{2}{29} - i \frac{5}{29}

解答ステップ

29 x^{2} - 4 x + 1 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 4 ) \pm ( - 4 ) ^{2} - 4 \cdot 29 \cdot 1}{2 \cdot 29}

簡素化

(- 4)^{2} - 4 \cdot 29 \cdot 1 : 10 i

x_{1, 2} = \frac{- ( - 4 ) \pm 10 i}{2 \cdot 29}

解を分離する

x_{1} = \frac{- ( - 4 ) + 10 i}{2 \cdot 29}, x_{2} = \frac{- ( - 4 ) - 10 i}{2 \cdot 29}

x = \frac{- ( - 4 ) + 10 i}{2 \cdot 29} : \frac{2}{29} + i \frac{5}{29}

x = \frac{- ( - 4 ) - 10 i}{2 \cdot 29} : \frac{2}{29} - i \frac{5}{29}

二次equationの解:

x = \frac{2}{29} + i \frac{5}{29}, x = \frac{2}{29} - i \frac{5}{29}
