x^3 − 27 = (x − 3)(x^2 + 3x + 9)
x^3 + 27 = (x + 3)(x^2 − 3x + 9)
(These follow from a^3 − b^3 = (a − b)(a^2 + ab + b^2) and a^3 + b^3 = (a + b)(a^2 − ab + b^2), with b = 3.)
x^3 + 27 = (x + 3)(x^2 − 3x + 9)
(These follow from a^3 − b^3 = (a − b)(a^2 + ab + b^2) and a^3 + b^3 = (a + b)(a^2 − ab + b^2), with b = 3.)
