1. Answer:

   2x-2+4=0

   Step-by-step explanation:

   so you have three options that a could equal.

   So you must substitute to find the answer

   2×2+4 does not equal 0, so we will try another

   2×1+4 does not equal 0, we will try the last one

   2x-2+4=0 so that is your answer

2. Answer:

   a= -2

   Step-by-step explanation:

   if a=2

   2(2)+4=0

   4+4=0

   8≠0

   if a= 1

   2(1)+4=0

   2+4=0

   6≠0

   if a= -2

   2(-2)+4=0

   -4+4=0

   0=0
