OpenStudy (anonymous):

lalaly!!! your back!! :-)))

OpenStudy (lalaly):

lols, i saw this once let a=b multiply by a a^2=ab add a^2 2a^2=ab+a^2 subtract 2ab 2a^2-2ab=a^2-ab 2(a^2-ab)=a^2-ab divide by a^2-ab 2=1

OpenStudy (anonymous):

a = b a^2 = a*b a^2-b^2 = a*b-b^2 (a+b)(a-b) = b(a-b) (a+b) = b a+a = a 2a = a 2 = 1

OpenStudy (anonymous):

hahahaha!! LOL!!!

OpenStudy (anonymous):

This is wrong because you are dividing by 0

OpenStudy (lalaly):

0?

OpenStudy (anonymous):

(a+b)(a-b) = b(a-b) a-b=0 (a+b) 0= b 0

OpenStudy (anonymous):

yes remember that a = b so a-b = 0 which is undefined

OpenStudy (lalaly):

lol haha ok

OpenStudy (anonymous):

so it is more like prove of 0=0
