2y-x(x-1) - 3(x-3)² y-2
------------------ = --------
(x-3)²(x-1) 2(4-x³)

#

That'd be my first bit...

#

Then I'd probably give up 💀

#

You'd cross multiply..

#

This is long..

#

i did that

#

im getting stuck after tho

#

i dont wanna expand and get powers of 4 and higher

#

after u move all the ys to one side

limber parrot
#

I GOT IT

#

You cancel down

#

Step 1: get everything with y's on one side

limber parrot
#

2y-x ~(x-1) ~ -3~(x-3)²~ •2(4x-x³)=y-2 ~(x-3)²~ ~(x-1)~
(2y-x)•2=y-2

#

How do you do the strikethrough

#

See the things with ~

#

Between every 2

#

Those get cancelled

#

I might have broke maths rules tho

#

I forgot but this makes sense..

limber parrot
#

Basically there's a (x-1) on both sides

#

So you cancel them out

#

There's also a (x+3)² on both sides

#

Cancel those out as well

novel hare
#

i dont think u can cancel out like that tho

limber parrot
#

Yeah I was debating that

novel hare
#

cus it has to be in each term to cancel out

#

still dont get it

#

help

limber parrot
#

I'm clueless as well now

#

Where the sixth formers at when you need them
