    additive inverse of x is -x that is we just switch the signs so additive inverse of -4b will be??

    when a+b = 0 we say a=-b when pq = 0, we say either p=0 or q=0 so, when (x+5)(y-6) =0 we say x+5 = 0 or y-6 = 0 x+5 = 0 just subtract 5 from both sides, what do u get? y-6 =0 just add 6 on both sides, what do u get?
