You My lifesaver Sir

[@atiemoportia5789]

please what do you mean by bracket differentiation

[@Ash-en4ul]

brilliant video sir

[@daramolavictoria8326]

Please sir can I expand the final answer

[@godhera5116]

Why did you multiply 4(3x-1)^3 by 3?

[@prodigykeith9191]

Am asking the same question...?

[@godhera5116]

@@prodigykeith9191 I got it...when you differentiate whats inside the bracket means (3x-1) the answer is only 3
dy/dx 3x = 3
dy/dx -1 =0 since its a constant...

[@joshuamonye4186]

Because (3) is a constant if it has a variable then you can leave it that way

[@FLASH24x]

you are amazing

[@ayeshasiddique1476]

thanks alot for the help 😇💜

[@asdasdasda5857]

Bro saved me

[@xzaiiii]

[@badiabaghdadi2628]

Why don't we also differentiate inside the brackets

[@hamzahwaheed9528]

I swear we do

[@uyandatatanqu2811]

Wow i actually get it

[@ryanlower7957]

thanks i was dying in class yesterday

[@Valb-sr1op]

at 7:59 can some1 explain why the number inside is 6? why not 2?

[@Valb-sr1op]

can you please tell me if that's because of the bracket or what ?????? I can't seem to understand why it's a six when the rest have been 2 or whatever is in the bracket?? thank u

[@ey4226]

For the answer to the question at 2:20 could you leave it as 10(x+2)^2 (2x+1) ?

[@Luke-ou7be]

Nothing much just go through your calculation if you're not satisfied with your answer
