 # Algebraic Fractions: Simplify by Denominators

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 […] # Algebraic Fractions: Simplify by Factorise

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 […] # Algebraic Fractions: Multiplication and Division

Okay. We’ve got three fractions but don’t panic.Just do exactly the same thing. Divide!We change it to a multiplication sign by flipping it. You can see that c squared is c times c.18 b is 6 times 3 b. So 18 is 6 times 3, isn’t it?The reason why I change to 6 times 3 […] # Algebraic Fractions: Multiplication

When we multiply we don’t have to worry. We don’t have to bother making the same denominators.When we multiply the numerators together and the denominators together that’s all you need to do. So it’s very simple.But what I’m going to do here guys you can see that 7m is just 7m but 15 is 3 […] # Factorising Monic Quadratic Trinomials Plus Minus Form

Transcript Now again, it’s a bit different because now we have positive here and negative here but don’t worry too much about this number guys because the the first thing you should consider is the factors of this one. Okay? Now it’s negative again. How do we make negative? Well we need to have plus […]
