Expert Answer:

  (x-a) is a factor of the polynomial p(x), if  p(a)=0. Also if x-a is a factor of p(x), then p(a) =0This is factor theorem                                                                                                                                                                         

If x+2 is a factor of polynomial 2x+4, then p(-2)=0

ie.  p(-2)= 2(-2) +4 =0
