Guys i have a really stupid math question:

When we have a perfect square e.g (4p-3)^2
the answer would be 16p^2 -24p +9
the reason is cuz of the formula a^2 -2ab + b^2 yeah
BUT
the -2ab part wouldn't it be (with the question above) -2*4p*-3 = +24p?
-- OR is does the 'b' (3) not include the negative sign, that's why it's -24p?

like i've legit forgotten 💀

I think the when you times 2*4p*-3 the negative at the front of 2 is not included so you just times the numbers 2x(4px3) and u just minus it from 16p^2. But basically when u do the part 2ab you don't include the negative signs when you times and you just include the minus sign once you figure out the 2ab part cause perfect squares is just a method and ur not substituting it into a formula

You're alright.

I also am in need of assistance...

How do people use these wretched things!? I've spent half an hour trying to get the sleeves in and all I've gotten and poor attempts and a bleeding finger...!!!

On second thought, I think I may give up and just put all the sleeves into one of those plastic folders.
