1-4x^3=0

解答

1 - 4 x^{3} = 0

解答

x = \frac{1}{3 4}, x = - \frac{1}{2 3 4} + \frac{3}{2 3 4} i, x = - \frac{1}{2 3 4} - \frac{3}{2 3 4} i

求解步骤

1 - 4 x^{3} = 0

将

1

到右边

- 4 x^{3} = - 1

两边除以

- 4

x^{3} = \frac{1}{4}

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}

x = 3 \frac{1}{4}, x = 3 \frac{1}{4} \frac{- 1 + 3 i}{2}, x = 3 \frac{1}{4} \frac{- 1 - 3 i}{2}

3 \frac{1}{4} = \frac{1}{3 4}

化简

3 \frac{1}{4} \frac{- 1 + 3 i}{2} : - \frac{1}{2 3 4} + \frac{3}{2 3 4} i

化简

3 \frac{1}{4} \frac{- 1 - 3 i}{2} : - \frac{1}{2 3 4} - \frac{3}{2 3 4} i

x = \frac{1}{3 4}, x = - \frac{1}{2 3 4} + \frac{3}{2 3 4} i, x = - \frac{1}{2 3 4} - \frac{3}{2 3 4} i

b^{4} - 6 b^{3} + 13 b^{2} + 36 = 0

5(y-3)^6-13(y-3)^4-6(y-3)^2=0

5 (y - 3)^{6} - 13 (y - 3)^{4} - 6 (y - 3)^{2} = 0

x^{3} - 5 = 0

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

x^{3} + x - 10 = 0
