**Reiny**, Friday, March 22, 2013 at 5:06pmafter a few tries I found f(4) = 0

so (x-4) is a factor

by synthetic long division I got

(x-4)(4x^2 + 35x - 9)

= (x-4)(x+9)(4x - 1)

What does the fact that

f(x) = -9 have to do with it.?

Did you mean to say: f(9) = 0 , that would have given me the clue that x+9 is a factor.
