Answer:
-9
Step-by-step explanation:
If the binomial is x + 4 = 0, then x = -4 That is the numbe that we will put "outside" and the rest of the numbers will go "inside". Using synthetic division and coefficients only:
-4| 1 7 3
First bring down the 1, multiply it by the -4, and put the product up under the 7:
-4| 1 7 3
-4
1
Now add 7 and -4 to get 3, multiply it by the -4, and put the product up under the 3:
-4| 1 7 3
-4 -12
1 3
Now add 3 and -12 to get a remainder of -9.
-4| 1 7 3
-4 -12
1 3 -9
