Simplify the expression:

12t^2 + 12t + 3
over
4t^2 - 1

i know that 3 is the GCF in the numerator, but i am so lost!

Pull out the three in the numerator. Now, break the numberator into two factors, and factor the denominator (difference of two squares). I suspect you will find a common factor that divides out.
