Use a^3 + b^3 = (a + b)(a^2 - ab + b^2), where a^2 is a squared, a^3 is a cubed. Note that 216 = 6^3.
x times x times x equals x cubed
x(x2 + 36)
3 times x times x times x
-2, 1.74 and 0.46
x cubed minus 216
64 x cubed minus y cubed is (4x - y)(16x^2 + 4xy + y^2)
x(x + 3)(x - 4)
(x + 6)(x^2 - 6x + 36)
(x - 1)(x - 1)(x - 1) - (x + 1)(x + 1)(x + 1)
Factor out the GCF and get X(X2-X+1).
x(x + 1)(x -1)
(x - 1)(x^2 + x + 1)
(x - 2)(x^2 + x + 3)
2163 = 216 x 216 x 216 = 10077696
