Answer:__9t²-4t-4__ t-6Step-by-step explanation:Let's focus on JUST (t+2)(t-2) first. We can do this:Multiply t by everything in the second equation:t²-2tThen multiply 2 by everything in the second equation:2t-4Then subtract those two, according to the second equation:t²-2t-2t-4Then simplify:t²-4t-4We aren't done yet, though. We have got to multiply the fractions. Our new equation after simplifying would be:9·t²-4t-4 (Let's forget about the denominator for a minute) So, our new top equation would be:9t²-4t-4Now, in our denominator, we can multiply t-2 by 3, so we get:t-2·3=t-6So, our fraction would now look like:__9t²-4t-4__ That fraction would be your answer. t-6 Sorry if I'm wrong :/
