Answer:

x = -1

Explanation:

We are to solve the cube root equation, ∛x – 1 + 2 = 0

Solve like terms; subtract 1 from 2 to get -1 (-1 + 2 = +1)

Therefore, ∛x + 1 = 0

Move +1 to the right side of the equation, since it does not contain the variable to solve for.

∛x + 1 = 0

Subtract 1 from both sides of the equation

∛x + 1 – 1 = 0 – 1

∛x = -1

Cube both sides of the equation in order to remove the radical on the left side

(∛x)^3 = (-1)^3

x = -1
