I'm not sure what the question is, so i'm going to just give you general steps. For these problems use FOIL(first, outer, inner, last)First: multiply the first term from (t Ã¢Ë†â€™ 4) and the t from (t+3).Outer: multiply the two outer term/numbers. so the first term from (t Ã¢Ë†â€™ 4) and the 3 from (t+3) Inner: multiply the two inside terms. The 4 in (t Ã¢Ë†â€™ 4) and the t in (t+3).Last: Multiply the last terms together. The 4 in (t Ã¢Ë†â€™ 4) and the 3 in (t+3)You should add all these up and combine like terms. Hopefully this would give you some hints. Again I'm not sure why (t Ã¢Ë†â€™ 4) came up.
