a=b for everything a,b belongs to IR*
a=b /xa
a
2=ab /-b
2a
2-b
2=ab-b
2(a-b)(a+b)=b(a-b) /:(a-b)
a+b=b but a=b
2b=b
2=1
solutionthere is something wrong in this ecuation, i chalange the forum to PM me(not reply) and tell me what is wrong,i especialy invite PKs like Sir Hubertus or Megan Fox to answer me
i wanna see if they are at the apropiate age to resolve this tipe of ecuations, i am sory if i did something wrondPeaople that get it correct:
