Determine the GCF of:
1)
First, notice that every term There are three terms) has an x in it. The lowest power of these is , so this can be factored from the trinomial.
Factor the x.
Further notice that in each term, every coefficient is a multiple of 2, so you can factor 2 from the trinomial.
Factor the 2.

2) Again, every term has an x to some power, and the lowest power is 1 . Also, every coefficient is a multiple of 3, so this can be factored.
