Answer:
1 (x+1)
------------------
3(x+2)
Step-by-step explanation:
4(x^2-1)
------------------
12(x+2) (x-1)
Factor the numerator
4(x-1) (x+1)
------------------
12(x+2) (x-1)
Cancel the x-1 from both the numerator and denominator
4 (x+1)
------------------
12(x+2)
Both 4 and 12 can be divided by 4
1 (x+1)
------------------
3(x+2)
This is as simplified as it can go
