so remember for us to be able to completely square. The first thing we do is we look at this term of the co official with our ex and we're going to first divide that by two and then square, and then we want to add and subtract this here. So we have X squared minus 10 x. And so then negative 10 over to that's negative. Five square. That would be 25. So we have lost 25 then over here we have minus 25. Now, this first part becomes a perfect square, so it's going to be acts plus something squared. And then we have minus 25 on the way we find out what to put here is by looking at this coefficient again, and we just divide it by two. Um, so it would just be minus five. And, um, yeah, let's just rewrite that So we don't have a plus minus B X minus five squared minus 25. And then this would be well, we get after we complete the square
