A: The 3-4-5 triangle rule uses this well known pythagorean triple. (-3, 2) and (-1,-1) *Click twice to draw a line. Rationalize radical denominator. Can we f, We're asked to add and simplify and we have the principle root of two x squared plus four times the principle root of eight plus three times the principle root two x squared plus the principle root of eight so we can do a little bit of adding, we can actually simplify first and then add or we can add first and then simplify but it looks like we can already add so lets try and do that so here, right over here, I have a principle root of two x squared and over here I have three principle roots of two x squared, well if I have one of something here and I have three of something here and i need to add them together I can put a one co-efficient out here to make it clear this is one of this thing and I have three of these things but if I have one of this thing and three more of these things and I add them together I am going to have four of those things, so this is four times the principle root of two x squared and that confuses a little bit, imagine that the whole principle root of two x squared was some variable lets say this whole thing was "a" and lets say that this whole thing was "a" as well, because its the same thing, you'd have one "a" plus three "a"'s which will give you four "a"'s, in this case "a" is all of this business right over here so we added those terms, and then we wanted to think about we have four principle roots of "a" and we have one more principle roots of "a", so same idea you have four of these things I am circling in magenta and you have one more of these things that I am circling in magenta, that one co-efficient is implicit so if I have four of something plus one more of something it becomes five of that something so plus plus five times the square root, plus five times the square root of eight and now we'll see if we can simplify this anymore, we have four of something and we have five of something else, so you can't just add these two things together, but maybe we can simplify this a little bit so we know that the principle root of two x squared, this is the same thing as, so let me write the four out front, so we have the four, and the principle root of two x squared is the same thing as the principle root of two times the principle root of x squared so I just rewrote this part over here and then we have plus five times, now eight can be written as a product of a perfect square and a not so perfect square, eight can be written as four times two, so lets write it that way so if we view this whole, this is the principle root, the square root of four times two, we can re-write this as the five times the square root of four, or the principle root of four times the principle root of two and what can we simplify here?
