So in order to get this equation into a similar for must answer format, it looks like we have to do something similar to completing two square, because all of the left left side so all the terms over here seem to be in a complete square. So in order to do that, we’re going to go ahead and think about this component first. And then we’re going to realize that in order to complete the square out of our X squared plus B X plus C term for just looking at the X scripless B X in order to complete the square, we just have to take the B and divide that by two and then square that whole quantity and then add that component to both sides of the equation formally, if we’re completing the square, so let’s go and try that. So if we have our b A six, that’s our be so we can say six Divided by two, which is three three squared is nine. So if we take X Square plus six X plus nine, then we would be able to get a pervasive where so then, if we were to put this into squares, we would get X Plus three swear. And…
