-6x^2+24x-504=0

解答

- 6 x^{2} + 24 x - 504 = 0

解答

x = 2 - 45 i, x = 2 + 45 i

求解步骤

- 6 x^{2} + 24 x - 504 = 0

使用求根公式求解

x_{1, 2} = \frac{- 24 \pm 2 4 ^{2} - 4 ( - 6 ) ( - 504 )}{2 ( - 6 )}

化简

2 4^{2} - 4 (- 6) (- 504) : 485 i

x_{1, 2} = \frac{- 24 \pm 48 5 i}{2 ( - 6 )}

将解分隔开

x_{1} = \frac{- 24 + 48 5 i}{2 ( - 6 )}, x_{2} = \frac{- 24 - 48 5 i}{2 ( - 6 )}

x = \frac{- 24 + 48 5 i}{2 ( - 6 )} : 2 - 45 i

x = \frac{- 24 - 48 5 i}{2 ( - 6 )} : 2 + 45 i

二次方程组的解是:

x = 2 - 45 i, x = 2 + 45 i

j(x)=x^2-x+1,j(2a)

j (x) = x^{2} - x + 1, j (2 a)
