Transcript 24! Let’s do the same kind of thing. I’m going to factorize. And you can see that here, x squared minus 16. 16 is…

Transcript 24! Let’s do the same kind of thing. I’m going to factorize. And you can see that here, x squared minus 16. 16 is…

Transcript You can see we want to add two different fractions. Now what I’m going to do before adding or doing anything, always as we…

Transcript Now you can see that we can’t take 2 out because 2 is not a common factor for 5 and 3. So we’re just…

Transcript Now I’m going to factorize them individually again but they’re not monic quadratic, so be very careful! So starting with here, I’m going to…

Transcript Okay let’s do the same thing but as I said guys, factorize anything if you can by taking out common factors. Here, 3 is…

Transcript Okay! So first of all, I took out the common factors for anything that I can. So here! See how x squared is common.…

Transcript Okay, it’s getting a little bit bigger but don’t be afraid. What do you need to do here guys?See how they already factorize the…

Transcript Okay, this time we’re adding but this time look at the denominators. We need to make common denominators in order to merge them together…

Transcript Okay, now we’ve got a fraction we want to simplify that fraction. Now if you have something well if you’re adding something on the…
