Find the polynomial that represents the volume of a cube if each side measure x plus 2?
The volume of a cube is L3 where L is the side length. If L = x + 2 then the volume is (x + 2)3 = x3 + 6x2 + 12x + 8.

What is the correct factorization for x3-15?
(X minus the cube root of fifteen) times (x squared plus the cube root of fifteen plus fifteen to the two thirds power)
How do you find cube of a number using log?
If log(x) = y then log(x3) = 3*log(x) = 3*y so that x3 = antilog(3*y) So, to find the cibe of x 1) find log x 2) multiply it by 3 3) take the antilog of the result.
What is the factor of x cube plus three x squared minus x minus three?
(x + 3)(x - 1)(x + 1)
How do you factor X to the third power plus Y to the third power?
x^3+y^3 Cube root of the first, x plus cube root of the last, y times What it takes to make the first number, x^2 Opposite sign, - Product of the two cube roots, -xy Then what it takes to make the last. (x+y)(X^2-xy+y^2)
Find out the square root of 9 then cube it?
The square root of 9 is the number you times by itself to get 9, so that's 3. Then to cube it you do 3 x 3 x 3 which is 27.
How do you find the cube root of a negative number?
If the negative number is "-a", then you can say the cube root is "-(cube root of a)" Because if you cube a negative number, you get a negative number. So if you cube root a negative number, you get a negative number. Ex) cube root of -8 = -2 Because (-2)^3 = -8 But if you want to find the complex cube roots, you can make an equation: "x^3=-a" or "x^3+a=0" We know one of the roots is "-(cube root of a)" so you can factor the equation by (x+(cube root of a)) And then you use the quadratic formula for the quadratic equation you're left with. Ex) x^3=-8 or x^3+8=0 Since -2 is a root, factor it by (x+2) x^3+8=(x+2)(x^2-2x+4) Using the quadratic formula, you get "1+i√3" and "1-i√3" Therefore the three cube roots of -8 is <"-2", "1+i√3", "1-i√3">
