It is the thing I have struggled with the most this year and the only area on my test I totally flunked. I can work out some answers but its really weak, like wet clay, and if someone could help me understand it would be much much appreciated ❤️
At this moment in time I unfortunately am not able to attach an image, due to my math book being taken in for marking : (
Thanks sm in advance!

what level of things are you being asked to factorise

#

just any random example will do

Which system are you? I think I might have some examples

i think its quite basic lol. I'll list a few examples : ) This is sort of what it ranges from and I dont really understand either. I'm a lost cause on the lower one ☺️ but I am aware about having to find the HCF, its just what I do from there.
32m + 40n-16
6mn + 4m²n-2mn²

nice, 8 indeed so how would i write everything in terms of '8'

#

in the sense that i can write 16 as 8*2 like that

#

multiples of 8 right? so 4m, 5n and 2 ?

worn lava
#

exactly
so that means you have 8(4m+5n-2)

#

i think!

#

does it need to be shortened at all?

worn lava
#

theres nothing more you could do to that

zenith mural
#

wait no i dont think it can

#

Don't forget the signs

#

They're worth half the mark

Thanks so much! I'll screenshot this to use as a basis when im stuck : - )

#

you seem fine with finding the hcf and that is most of the work

zenith mural
#

I'll use ths to try work out the harder one

Check out this video he's great for cramming

#

Not for actual studying though probably look at better sources if you want a deeper understanding

Thanks sm!
