(x^2)/3 x=6

解答

\frac{x ^{2}}{3} x = 6

解答

x = 318, x = - 318 \frac{1}{2} + 318 \frac{3}{2} i, x = - 318 \frac{1}{2} - 318 \frac{3}{2} i

求解步骤

\frac{x ^{2}}{3} x = 6

化简

\frac{x ^{3}}{3} = 6

在两边乘以

3

\frac{3 x ^{3}}{3} = 6 \cdot 3

x^{3} = 18

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 = 318, x = 318 \frac{- 1 + 3 i}{2}, x = 318 \frac{- 1 - 3 i}{2}

化简

318 \frac{- 1 + 3 i}{2} : - 318 \frac{1}{2} + 318 \frac{3}{2} i

化简

318 \frac{- 1 - 3 i}{2} : - 318 \frac{1}{2} - 318 \frac{3}{2} i

x = 318, x = - 318 \frac{1}{2} + 318 \frac{3}{2} i, x = - 318 \frac{1}{2} - 318 \frac{3}{2} i

(x+2)(x^2+6x+10)=0

(x + 2) (x^{2} + 6 x + 10) = 0

(2x-1)^3-4x(2x-3)=5

(2 x - 1)^{3} - 4 x (2 x - 3) = 5

solvefor a,a^54^{-2}=2

so l v e f or a, a^{5} 4^{- 2} = 2

y^{3} = - 27

x^{3} - 2 x^{2} - 12 x = 0
