solvefor x,(x-1)(x-1)(x-1)=y

解答

求解

x, (x - 1) (x - 1) (x - 1) = y

解答

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

求解步骤

(x - 1) (x - 1) (x - 1) = y

化简

(x - 1)^{3} = y

对于

g^{3} (x) = f (a)

解为

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

解

x - 1 = 3 y : x = 3 y + 1

解

x - 1 = 3 y \frac{- 1 + 3 i}{2} : x = \frac{2 - 3 y}{2} + i \frac{3 3 y}{2}

解

x - 1 = 3 y \frac{- 1 - 3 i}{2} : x = \frac{2 - 3 y}{2} - i \frac{3 3 y}{2}

解为

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