Factoring precalc

im stuck on factoring (x1)(2x^3+13x^2+8x35)
do i use synthetic division? if so what zero?
thnks.

synthetic division would be an easy way to check for roots p/q where p divides 35 and q divides 2.
Check for whole roots first: 1,5,7,35
A little trial shows that
2x^3+13x^2+8x35 = (x+5)(2x^2+3x7)
