Question

Which restriction is appropriate for the variable 4a + 12 / a + 3

Answer 1

The restriction is at a=-3

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

Answer 2

I'll presume the slash is the fraction bar and the questioner is asking about

`(4a+12)/(a+3)`

That always equals 4 except when
`a=-3`

So the restriction is

Answer: a ≠ -3
