I have 4x-15 / (x+3)(x+2)
I ended up with -27 for the first one which is A, though I think A is -A because the answer for that bracket is
when x=-3 (-3+2) = -1A, so, -27 = -A. do the minus's cancel leaving only 27? I always get confused with the minus's. is there somewhere with the rules for minus written down so I can memorise them?
and -23 for the second one which is B
any help would be greatly appreciated!!!
many thanks, hope your all well!!!
and remember only two months left to Christmas!!!!
