Question

Can some one help me trough this problem?

Factor f(x) = x4 + x3 – 8x2 + 6x + 36 completely

mathmale · Answer

I'd start by listing all the possible integer factors of 36, both positive and negative.  
If you know synthetic division, that would be the fastest method for determining whether or not any particular integer factor of 36 is actually a root of the given polynomial.  
Know synth. div.?
