(x + 4)(x - 2)(x - 2)
or
(x + 4)(x - 2)2
(a - 2)(a^2 + 6)
Factor out the GCF and get X(X2-X+1).
(x - 2)(x^2 + x + 3)
(x - 5)(x^2 + 1)
(x + 2)(3x - 1)(3x + 1)
(x - 1)(x - 1)(x - 1) - (x + 1)(x + 1)(x + 1)
x(x - 19)(x - 1)
n(2n - 1)(2n + 7)
x³ + x² - 3x - 3 = (x + 1)(x + √3) (x - √3).
x³ - x² + x - 3 (x² + 1)(x - 1) - 2
x3 + 4x2 - 16x - 64 = (x + 4)(x + 4)(x - 4).
