I'll presume the slash is the fraction bar and the questioner is asking about
[tex]\dfrac{4a+12}{a+3}[/tex]
That always equals 4 except when [tex]a=-3[/tex]
So the restriction is
Answer: a ≠ -3
Answer:
The restriction is at a=-3
Step-by-step explanation:
You need to see if there are like terms. If there are that is a hole. For example you can a 4 out of the equation like so.
4(a+3)/a+3.
since they both have a+3 that is a hole. so a+3=0 so a=-3 is a restriction
