y^3=-9

解答

y^{3} = - 9

解答

y = - 39, y = - \frac{3 9 ( - 1 + 3 i )}{2}, y = - \frac{3 9 ( - 1 - 3 i )}{2}

求解步骤

y^{3} = - 9

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}

y = 3 - 9, y = 3 - 9 \frac{- 1 + 3 i}{2}, y = 3 - 9 \frac{- 1 - 3 i}{2}

3 - 9 = - 39

化简

3 - 9 \frac{- 1 + 3 i}{2} : - \frac{3 9 ( - 1 + 3 i )}{2}

化简

3 - 9 \frac{- 1 - 3 i}{2} : - \frac{3 9 ( - 1 - 3 i )}{2}

y = - 39, y = - \frac{3 9 ( - 1 + 3 i )}{2}, y = - \frac{3 9 ( - 1 - 3 i )}{2}

-λ^3+5λ^2-6λ=0

- λ^{3} + 5 λ^{2} - 6 λ = 0

a x + b x^{3} = 0

1 - x^{2} = 24 x^{3}

a^{3} = 5 (3) - 1

(3x-1)^2=(3x-1)^3

(3 x - 1)^{2} = (3 x - 1)^{3}
