-1+v^3=-3

解答

- 1 + v^{3} = - 3

解答

v = - 32, v = \frac{3 2}{2} - i \frac{3 2 3}{2}, v = \frac{3 2}{2} + i \frac{3 2 3}{2}

求解步骤

- 1 + v^{3} = - 3

将

1

到右边

v^{3} = - 2

对于

x^{3} = f (a)

解为

x = 3 f (a), 3 f (a) \frac{- 1 - 3 i}{2}, 3 f (a) \frac{- 1 + 3 i}{2}

v = 3 - 2, v = 3 - 2 \frac{- 1 + 3 i}{2}, v = 3 - 2 \frac{- 1 - 3 i}{2}

3 - 2 = - 32

化简

3 - 2 \frac{- 1 + 3 i}{2} : \frac{3 2}{2} - i \frac{3 2 3}{2}

化简

3 - 2 \frac{- 1 - 3 i}{2} : \frac{3 2}{2} + i \frac{3 2 3}{2}

v = - 32, v = \frac{3 2}{2} - i \frac{3 2 3}{2}, v = \frac{3 2}{2} + i \frac{3 2 3}{2}

x (x + 3) (x - 2) = 0

x^3+6x^2-36x+2=0

x^{3} + 6 x^{2} - 36 x + 2 = 0

10 (2 x - 1)^{4} = 0

2x^6+88x^2=30x^4

2 x^{6} + 88 x^{2} = 30 x^{4}

2(x+7)(25x^2-49)=0

2 (x + 7) (25 x^{2} - 49) = 0
