Add 2 to both sides of the equation.

So, I have this half-done equation, and the next step is to add 2 to both sides, how do I do that? Please help with a legit answer, thankyou so much!
x^3=∛(x-2)

Respuesta :

Answer:

x = -1.135 (approx).

Step-by-step explanation:

x^3 = ∛(x - 2)

Cube both sides:

x^9 = x - 2

Subtract x and add 2 to both sides:

x^9 - x + 2 = 0

We could solve this for real roots by drawing a graph.

I did this and got one root  x = -1.135 (approx).

The other 8 roots are complex.
