36x^2+16x+2=0

解答

36 x^{2} + 16 x + 2 = 0

解答

x = - \frac{2}{9} + i \frac{2}{18}, x = - \frac{2}{9} - i \frac{2}{18}

求解步骤

36 x^{2} + 16 x + 2 = 0

使用求根公式求解

x_{1, 2} = \frac{- 16 \pm 1 6 ^{2} - 4 \cdot 36 \cdot 2}{2 \cdot 36}

化简

1 6^{2} - 4 \cdot 36 \cdot 2 : 42 i

x_{1, 2} = \frac{- 16 \pm 4 2 i}{2 \cdot 36}

将解分隔开

x_{1} = \frac{- 16 + 4 2 i}{2 \cdot 36}, x_{2} = \frac{- 16 - 4 2 i}{2 \cdot 36}

x = \frac{- 16 + 4 2 i}{2 \cdot 36} : - \frac{2}{9} + i \frac{2}{18}

x = \frac{- 16 - 4 2 i}{2 \cdot 36} : - \frac{2}{9} - i \frac{2}{18}

二次方程组的解是:

x = - \frac{2}{9} + i \frac{2}{18}, x = - \frac{2}{9} - i \frac{2}{18}
