Find factor/s and zeros of the polynomial: f(x) = 6x - 18

Given Polynomial, f(x) = 6x - 18
Now, Equating the above polynomial with 0, we get:

=> 6x - 18 = 0

=> x = 3

And 

f(x) = 6x - 18 = 6(x - 3)

Thus, the zero of the given polynomial: x = 3

And, factors of the given polynomial = 6, (x - 3)
