Question: For each polynomial function: a) Find the rational zeros and then the other zeros; that is, solve f (x) = 0. b) Factor f (x)

For each polynomial function:
a) Find the rational zeros and then the other zeros; that is, solve f (x) = 0.
b) Factor f (x) into linear factors.
1. f(x) = x3 + 3x2 - 2x - 6
2. f(x) = x3 - x2 - 3x + 3
3. f(x) = 3x3 - x2 - 15x + 5
