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 4 squared, so that’s why I changed it like that. And see here, guys. That, I don’t want negative in front of my x. I kind of swap these around. […]

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 usual, factorize! So see how here we can see that x is common factor and here x is also a common factor, so we’ll take those common factors out like […]

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 going to go straight to the cross method. But this time, it’s going to be x and 2x because x times 2x makes 2x squared, so it’s going to be […]

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 use x and 2x and the other one will be 1 which becomes 2x and negative 1, negative x and 2x minus x is x which is right. Now for […]

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 common! Here, x is common! So I just took them out as common factors. That’s the first thing I always want to do. Now let’s factorize the numerators by using […]

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. So I took the x squared out and here, 16. We know that 16 is 4 squared. So this will be a difference of two squares. So I’ve simplified it, […]

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 denominators for you. What I want you to do is put in all the different types of varieties of factors on the denominator. Now you’re probably going what does that […]

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 right? But the denominators, they’ve got some pronumerals involved. So what do we do? Remember guys what I said before in one of the earlier questions I said if you […]

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 numerator and adding or subtracting something on the denominator. See if you can factorize anything okay? Factorizing is a good thing to use when you’re trying to simplify fractions, so […]
