View Full Version : What is wrong with this problem? Mors 05-23-03, 01:24 AM a=b a*a = a*b a^2 = ab a^2 - b^2 = ab - b^2 [(a-b)(a+b)] = b(a-b) [(a-b)(a+b)] = b(a-b) ..... (a-b)......... (a-b) a+b = b b+b = b 2b = b ? Mors 05-23-03, 01:38 AM Beverages and office supplies will be rewarded to the first person to get it! everneo 05-23-03, 01:52 AM ... .. 2b = b b+b = b b = b - b b = 0 a = b a = b = 0 = -0 = 0*0 = n*0 etc...:bugeye: Mors 05-23-03, 01:57 AM nope, sorry, not the answer i was looking for. suppose a and b did not = 0 everneo 05-23-03, 02:16 AM Originally posted by Mors nope, sorry, not the answer i was looking for. suppose a and b did not = 0 how ? also a-b = 0 ; dividing by this in a derivation is surprising.
