-6x^2+18x-12=0

解答

- 6 x^{2} + 18 x - 12 = 0

解答

x = 1, x = 2

求解步骤

- 6 x^{2} + 18 x - 12 = 0

使用求根公式求解

x_{1, 2} = \frac{- 18 \pm 1 8 ^{2} - 4 ( - 6 ) ( - 12 )}{2 ( - 6 )}

1 8^{2} - 4 (- 6) (- 12) = 6

x_{1, 2} = \frac{- 18 \pm 6}{2 ( - 6 )}

将解分隔开

x_{1} = \frac{- 18 + 6}{2 ( - 6 )}, x_{2} = \frac{- 18 - 6}{2 ( - 6 )}

x = \frac{- 18 + 6}{2 ( - 6 )} : 1

x = \frac{- 18 - 6}{2 ( - 6 )} : 2

二次方程组的解是:

x = 1, x = 2
