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
