Thread: help factoring polynomial

hi, i really wanna ask a question is there any easier way to factor this polynomial 6x^4 + x^3 - 8x ^2 -x + 2 ,
and i have one more question, when do use the integral zero theorm P (b)=0and the factor theorm P ( b/a ) = 0. i just wanna know the difference , and when to use which. thanks

Note that:

p(1) = 0.

p(-1) = 0.

arghh i get what u mean , how 1 is + and - , but can anyone answer my other question lol thanks
