Which polynomials has 1, -3, and 5 as zeros?
P(x) = (x - 1)(x - 3)(x - 5)
P(x) = (x - 1)(x + 3)(x - 5)
P(x) = (x + 1)(x + 2)(x + 5)
P(x) = (x - 1)(x - 2)(x - 5
P(x) = (x - 1)(x - 3)(x - 5)
P(x) = (x - 1)(x + 3)(x - 5)
P(x) = (x + 1)(x + 2)(x + 5)
P(x) = (x - 1)(x - 2)(x - 5

x=a is a zero if (x-a) is a factor
so, #3 is out, since (x-1) is not a factor
now try the rest
