What Is X Cubed- 8 Over X-2

X cubed divided by x-2 is . . .?

since you dont have the value for x I will assign a random number

if x=2 then you will have

2^3/2^-2
2*2*2/(1/2^2)
6/(1/2*2)
6/(1/4)
6/.25
24

What is x if x cubed equals 1?

If x^3 = 1, then taking the cube root of both sides gives you x = 1. If you're only looking for real solutions, then stop here.

If you're looking for complex solutions, then that's another story. To find the other two solutions, start with x^3 - 1 = 0 and factor as the difference of two cubes:
(x - 1) (x^2 + x + 1) = 0
Use the quadratric formula to solve x^2 + x + 1 = 0, which gives you your two complex solutions.

How do you factor X Cubed + 8?

a³ + b³ = (a + b)(a² -ab + b²)
Let a = x and b = 2
=> x³ + 2³ = (x + 2)(x² - 2x + 2²)
=> x³ + 8 = (x + 2)(x² - 2x + 4)

Factor x cubed plus 8 over x plus 2?

??????????????????????

How do you factor x cubed minus 8?

1) You might notice that if x = 2,
x^3 = 8, so x^3 - 8 = 0
That should tell you that (x - 2) is a factor
As this was a cubic the other factor is a quadratic,
(which might or might not itself give linear factors).
The first and last terms of the quadratic are obvious
but we do not yet know the coefficient of the x term.
(x - 2)(x^2 + kx + 4) = x^3 - 8
Equating coefficients of x
-2k + 4 = 0
k = 2, so now we have
x^3 - 8 = (x - 2)(x^2 + 2x + 4)

2. 36x^2 - 16 = 4(9x^2 - 4)
Then using a "difference of two squares"
36x^2 - 16 = 4 (3x - 2)(3x + 2)

What is (x+2)cubed? idk how to foil it three times?

First multiply (x+2)(x+2) = (x^2 + 4x + 4)(x+2) = x^3 + 2x^2 + 4x^2 + 8x + 4x + 8

x^3 + 6x^2 + 12x + 8

How do you factor x cubed minus 3x minus 2?

If you tried to solve x³ - 3x - 2 = 0, then x = -1 is a solution. (use rational root test to get possible choices to check)

If x = -1, then x + 1 = 0, so (x + 1) must be a factor. (by factor theorem)

so divide x³ - 3x - 2 by (x+1) to get x² - x - 2

so, x³ - 3x - 2 = (x+1)(x² - x - 2)

now factor x² - x - 2 to get

x³ - 3x - 2 = (x+1)(x - 2)(x + 1)

How do you solve x(cube)-8=0? and what are the answers to this equation?

x = 2
2x2x2 - 8 = 0

to solve: x**3 - 8 = 0
x**3 = 8
cubed root of 8 = 2
