Why do you people want equations solved when you present them incorrectly. You must mean.............
X^3 - 8 = 0
add 8 to each side
X^3 - 8 + 8 = 0 + 8
X^3 = 8
take the cubic root of each side and you should know that 2 is the cubic root of 8
X = 2

X to the 3rd power -8?
x^3 -8 is two terms of an algebraic expression
What is x to the 3rd power minus 3x to the 2nd power minus 28x?
x3 - 3x2 - 28x = x (x2 - 3x - 28) = x (x - 7) (x + 4)The numerical value of all this, of course, depends on the value of 'x',and it can change in a flash whenever the value of 'x' changes.
