i got:

P:-1,+1

q: -1,+1,-5,+5,+25,-25,

there are additional factors for the constant, what are they and how do i go about finding them? i dont want pts taken off from my exam by not finding ALL the factors.

and when i solve this problem, should i use the quadratic function or should i continue using synthetic division until its completely factorized? i got the answer, i just continued using synthetic division, i see that u can also use the quadratic function, question is does it matter what i use?

thanks!
