Answer:
The answer to your question is: letter A
Step-by-step explanation:
See the picture below
When we divide the polynomial by the factor the result is zero, that's why letter A is the factor.
When we divide the polynomial by B, C or D the residue is not zero, then they are not factors.
Justify means plug answer in and verify
so distribute 8(3-7x)=24-56x
143=7+24-56x
143=31-56x
minus 31 both sides
112=-56x
divide both sides by -56
-2=x
justify
plug it back
143=7+8(3-7x)
143=7+8(3-7(-2))
143=7+8(3-(-14))
143=7+8(3+14)
143=7+8(17)
143=7+136
143=143
true
x=-2
