how would I do this

[gilded estuary]

And what topic does it fall under if anyone knows

[proper pasture]

Alr so have you expanded it

[gilded estuary]

yeah idk why I rubbed it out 😢😢

[proper pasture]

Alr so you get

12x + 28 - 18x - 2c = dx + 90

[gilded estuary]

Yea

[proper pasture]

Combines to get -6x + 28 - 2c = dx + 90

[gilded estuary]

yeah

[proper pasture]

The coefficient of x on left hand side is -6 and on the right hand side is d so if you’re saying they’re identical (because of the equal sign but with 3 lines idk what you call it) then d = -6

[gilded estuary]

WAITT

sorry for caps

ohh

[proper pasture]

So how would u find c

[gilded estuary]

UHH

you’d have to move something

like dx + 90

I’m not sure which one you’d have to move in order to get c

[proper pasture]

To get c you could either sub in -6 for d

Or you could equate the constants

2nd option is better

[gilded estuary]

what does equate the constants mean

[proper pasture]

Setting the constants terms on one side of the eqn equal to the constant terms on the other side of the eqn

[gilded estuary]

sorry I can’t rlly visualise that 😭

[proper pasture]

Watch a video on solving identities

[gilded estuary]

ohh is that what the topic is called

[proper pasture]

Thats the topic

[gilded estuary]

never learnt it

[proper pasture]

Yeah

[gilded estuary]

ohhh okkk

thank u !!

[proper pasture]

Srry I couldn’t explain it well

Lol

[gilded estuary]

nah you explained it well it’s just that it’s new to me so it won’t come quick as I am slow

NO IDEA 😭😭

[lavish knoll]

I seen it in a l2 fm aqa paper

[gilded estuary]

it’s strange

[lavish knoll]

yeah I don’t think that’s meant to be there

@thick stirrup it’s a fm gcse topic right

[thick stirrup]

uh

idk

but I could see this on a normal gcse paper tbh

[lavish knoll]

I’ve only seeen this on a l2

[thick stirrup]

but those are probably identites you have to learn?

[lavish knoll]

Maybe idk

[thick stirrup]

here it's just equating things

[proper pasture]

It’s on the edexcel gcse spec

[lavish knoll]

Ah alright

[gilded estuary]

I do Aqa

how can I check if it will be on my spec

[proper pasture]

It’s on the Aqa spec too

[gilded estuary]

NOOOO

😢

[proper pasture]

Did you watch the vid?

It’s not too bad once you understand it

[gilded estuary]

nah I’ve had appointments since 7 am 😢😢

still not done

I will when I get back home
