x^2+6x+32=0

解答

x^{2} + 6 x + 32 = 0

解答

x = - 3 + 23 i, x = - 3 - 23 i

求解步骤

x^{2} + 6 x + 32 = 0

使用求根公式求解

x_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 \cdot 1 \cdot 32}{2 \cdot 1}

化简

6^{2} - 4 \cdot 1 \cdot 32 : 223 i

x_{1, 2} = \frac{- 6 \pm 2 23 i}{2 \cdot 1}

将解分隔开

x_{1} = \frac{- 6 + 2 23 i}{2 \cdot 1}, x_{2} = \frac{- 6 - 2 23 i}{2 \cdot 1}

x = \frac{- 6 + 2 23 i}{2 \cdot 1} : - 3 + 23 i

x = \frac{- 6 - 2 23 i}{2 \cdot 1} : - 3 - 23 i

二次方程组的解是:

x = - 3 + 23 i, x = - 3 - 23 i
