partial fractions in maths?
why is the repeated bracket done differently to if it was just on its own??
It is done like this:
_A_ +_B_+_C_
(x+2) (x-4) (x-4)^2
why is that not done like this:
_A_+_B_+_C_
(x+2) (x-4) (x-4)
I know it doesn't work but why??
I suppose but why can't it be treated as if it was two separate brackets (x-4)(x-4). i suppose i see what you mean though

The LCD is (x+2)(x-4)^2. Therefore, you must have the term C/(x-4)^2
