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^3 -8 is two terms of an algebraic expression
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.
-8 x -8 = +16anything which is minus x minus = plus (- x - = +)
x4+6x3-2x-12 (x3-2)(x+6)
Organize this expression into groups of like terms, so that it is easy to combine.7x^2 - 8x + 2x - x^3 + 9 - 8Answer:7x^2 - 6x -x^3 + 1

14x squared minus 7x to the 3rd power can be factored to 7x2(2-x).

x^3 -8 is two terms of an algebraic expression
(x + 1)(x - 8)
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.
x4-8 = 0 x4 = 8 Eradicate the the power of 4 x = 1.681792831 Check: 1.6817928314 = 8.000000009 which is just about correct.
-8 x -8 = +16anything which is minus x minus = plus (- x - = +)
Well, darling, when you divide x to the power of 8 by x squared, you subtract the exponents. So, x to the power of 8 divided by x squared is x to the power of 8 minus 2, which simplifies to x to the power of 6. So, there you have it, x to the power of 6 is the sassy answer you're looking for.
