So in order for us to complete this square, remember, What we're going to do is we first look at this coefficient with our ex and we're going to add when we take that term and divided by two and then square. And then we also need to subtract it because if we add something, we also need to subtract. And now let's go on and write this house. We have X square plus 12 x so 12 over to a six square were to be 36 then minus 36. So now this part here is going to become a perfect square. So it be X plus something squared. And then we have minus 36 out here and now the way we get this middle term is we just take what We are not the military, but what we put right here. We just look at this term here and divided by two would be 12 divided by two or six, and so that this is going to be our perfect square.
