I know this might sound a bit silly, but I usually do well in math. It's just that the teacher gives us so much info all at once that my brain gets totally overwhelmed. He's really good at explaining, but sometimes goes into too much detail.
I don't want to rely on ChatGPT or just memorize things—I really want to understand and learn it for real.

what's the goal? simplify all of these or what
break it down. i guess u learnt that a(b+c)=ab+ac , and a(b-c)=ab-ac
now, let's apply this.
a) (2x-4).(2-x).
let's suppose 2x-4= a ; 2=b; x=c here. then, it equals (2x-4).2x - x.(2x-4)
let's break it down even further here.
(2x-4).2x = 2x.2x - 4.2x = 4x^2 -8x
x(2x-4)= 2x.x - x.4= 2x^2 - 4x
now, let's connect all of these.
(2x-4).(2-x)= (2x-4).2x - x.(2x-4)=2x.2x - 4.2x - (2x.x - x.4)=4x^2 -8x- (2x^2 - 4x)=4x^2-8x-2x^2-4x=2x^2-12x
same for b and c

I... Dont understand in that way.

u can expand it to
2x(-x+2) -4(-x+2)
_ _
do u understand
why
also for number 3
there is a useful formula
(a+b)²=a²+2ab+b²
midnight hazel
u expand it
bobo duck how we write it in math form
is there a command or js like
