According to the rational root theorem, which is a factor of the polynomial

vekshin1

Supposing 2x-7 were a factor, then 7/2 would be a root. Use synth. div. to determine whether 7/2 actually is a root:

__________________________
7/2 / 6 -21 -4 24 -35
21 0 -14 35
----------------------------------------
6 0 -4 10 0

Since the remainder is zero, 7/2 is a root and 2x - 7 is a factor.

You could check out the other possible factors in the same manner.
