Anyone good at maths gcse / nat5 ?

[Righttoo]

I was wondering if anyone could show me the working for this example. Express as a single fraction in its simplest form.

(It's a while since I've done algebra in anger, so hopefully this is simplest form!)

Trying again as image wasn't showing

@redskydarknight Can you explain why you can just stick a "y" after the second numerator to give 2x²y rather than having to put it in brackets i.e. y(2x²)? Does it mean the same thing?

It means the same thing. In algebra putting two letters next to each other means that they are multiplied together - the same as putting them in brackets.

The version without brackets is probably preferred as it's less writing, but you can go with whatever format is clearer to you.

Sorry. Thanks for your reply. My photo not very good. The two terms have a dividing symbol. Not a adding symbol between

Thanks for explaining!

Would this be one of the harder Nat 5 questions?

Ignore my photo, it's wrong
The second line should be turned upside down when multiplying

Have you not forgotten to invert the second fraction before multiplying?

Crossed!

Ignore my calculations at the side as I was testing if you get the same answer when plugging in test values

I think you can also simplify further. See my photo here.

The main reason I was asking is my ds is using a tutor. And in his working he does something different. And I find it confusing. But I wasn’t sure if it was a better way.

This is the method. Where he starts cancelling things out before any multiplication.

I am trying to work out if this is maybe how they teach it now?
