so we have to be minus two. All squared. So whenever we see that squared exponents, that just means we're gonna multiply the binomial by itself. So we have three t minus two times three B minus two. And because we're not supplying to buy no meals, we're gonna use the foil minted. So what have the first chowder, then enter terms. And in the last terms, this just helps us keep everything orderly. Someone for the 1st 3 many times three be not only those 29 b squared because we have those explain it. Don't do the outer terms so negative two times three is negative six and then just bring on that b turned it. Enter terms and same thing here. Negative two times three is negative. Six. Hey! And almost part of the last times negative times Negative gives us positive for so because he's too in terms in the middle, have the same Explain it. We can combine the coefficients so have nine b squared in the year six minus six is negative 12 b and then plus fours
