-6x^2+6x-162=0

解答

- 6 x^{2} + 6 x - 162 = 0

解答

x = \frac{1}{2} - i \frac{107}{2}, x = \frac{1}{2} + i \frac{107}{2}

求解步骤

- 6 x^{2} + 6 x - 162 = 0

使用求根公式求解

x_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 ( - 6 ) ( - 162 )}{2 ( - 6 )}

化简

6^{2} - 4 (- 6) (- 162) : 6107 i

x_{1, 2} = \frac{- 6 \pm 6 107 i}{2 ( - 6 )}

将解分隔开

x_{1} = \frac{- 6 + 6 107 i}{2 ( - 6 )}, x_{2} = \frac{- 6 - 6 107 i}{2 ( - 6 )}

x = \frac{- 6 + 6 107 i}{2 ( - 6 )} : \frac{1}{2} - i \frac{107}{2}

x = \frac{- 6 - 6 107 i}{2 ( - 6 )} : \frac{1}{2} + i \frac{107}{2}

二次方程组的解是:

x = \frac{1}{2} - i \frac{107}{2}, x = \frac{1}{2} + i \frac{107}{2}
