Factor the polynomial f(x) = x5 + 2x3 8x216 and find its real zeros using the Zero Product Property. f(x) = (238) (x + 2); real zero at x = 2 f(z) = (x-2) (x + 2x + 4) (2-2), real zeros at x = 2, 2 f(x) = (x-2) (x + 4x + 4) (x + 2): real zeros at x = -2( multiplicity 2), 2 f(x) = (1-2) (x + 2x + 4) (x + 2): real zero at x = 2
