6x^2-2x+1=0

解答

6 x^{2} - 2 x + 1 = 0

解答

x = \frac{1}{6} + i \frac{5}{6}, x = \frac{1}{6} - i \frac{5}{6}

求解步骤

6 x^{2} - 2 x + 1 = 0

使用求根公式求解

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

化简

(- 2)^{2} - 4 \cdot 6 \cdot 1 : 25 i

x_{1, 2} = \frac{- ( - 2 ) \pm 2 5 i}{2 \cdot 6}

将解分隔开

x_{1} = \frac{- ( - 2 ) + 2 5 i}{2 \cdot 6}, x_{2} = \frac{- ( - 2 ) - 2 5 i}{2 \cdot 6}

x = \frac{- ( - 2 ) + 2 5 i}{2 \cdot 6} : \frac{1}{6} + i \frac{5}{6}

x = \frac{- ( - 2 ) - 2 5 i}{2 \cdot 6} : \frac{1}{6} - i \frac{5}{6}

二次方程组的解是:

x = \frac{1}{6} + i \frac{5}{6}, x = \frac{1}{6} - i \frac{5}{6}
