Remember 8 = 2^(3) & 27x^(3) = (3x)^3
Hence
2^(3) - (3x)^3 is of the form
x^(3) - y^(3) = ( x - y)(x^2 + xy + y^2)
Hence
2^(3) - (3x)^(3) = ( 2 - 3y)(2^(2) + (2)(3y) + (3y)^(2)) =>
2^(3) - (3y)^(3) = (2 - 3y)(4 + 6y + 9y^(2)) -
Done!!!!!

What is the factored form of 27x cubed minus eight?
27X^3-8 = 0 27X^3 = 8 X^3 = 8/27 X = cubic root of 8/cubic root of 27 = 2/3
How do you factor the expression x cubed minus 8?
(x3 - 8) is factored thus: (x - 2)(x2 + 2x + 4) The easiest way to do this is to remember the formula: (a3 - b3) = (a - b)(a2 + ab + b2)
How do you factor 9x squared minus 64?
(3x + 8)(3x - 8)

(2x + 5)(4x^2 - 10x + 25)
How would the expression x cubed minus 8 be rewritten using the difference of cubes?
Answer: (x - 2)(x² + 2x + 4)Factor the difference of cubes:a³ - b³ = (a - b)(a² + ab + b² )note 8 = 2³ = 8 ⇒ b = 2 , with a = xSox³ - 8= x³ - 2³= (x - 2)(x² + 2x + 2²) = (x - 2)(x² + 2x + 4)
What is the factored form of 27x cubed minus eight?
