6x^2+11x=-3

解答

6 x^{2} + 11 x = - 3

解答

x = - \frac{1}{3}, x = - \frac{3}{2}

+1

十进制

x = - 0.33333 \dots, x = - 1.5

求解步骤

6 x^{2} + 11 x = - 3

将

3

para o lado esquerdo

6 x^{2} + 11 x + 3 = 0

使用求根公式求解

x_{1, 2} = \frac{- 11 \pm 1 1 ^{2} - 4 \cdot 6 \cdot 3}{2 \cdot 6}

1 1^{2} - 4 \cdot 6 \cdot 3 = 7

x_{1, 2} = \frac{- 11 \pm 7}{2 \cdot 6}

将解分隔开

x_{1} = \frac{- 11 + 7}{2 \cdot 6}, x_{2} = \frac{- 11 - 7}{2 \cdot 6}

x = \frac{- 11 + 7}{2 \cdot 6} : - \frac{1}{3}

x = \frac{- 11 - 7}{2 \cdot 6} : - \frac{3}{2}

二次方程组的解是:

x = - \frac{1}{3}, x = - \frac{3}{2}
