rcsoar4fun rrKey Veteran Boise, Idaho  Tonight a friend asking me to help with this, I am way out of practice. I keep screwing up in the same place, I can prove its wrong, but cannot find where it goes wrong. Any help?I give up on Loctite, nothing lasts long enough to vibrate loose anymore.

michael88997 rrElite Veteran Lewisville,Tx  i dont understand how you get from the first step to the second step

michael88997 rrElite Veteran Lewisville,Tx  you cant get (aB)(a+b) from a squared b squared

eggmcmuffinplz rrElite Veteran Los Angeles, CA  y = mx + b

rcsoar4fun rrKey Veteran Boise, Idaho  I know its wrong a=b=1 means A and B are 1 but; Final solution is A+B=A but that means B=0.I give up on Loctite, nothing lasts long enough to vibrate loose anymore.

michael88997 rrElite Veteran Lewisville,Tx  ok the a squared on both sides cancells out... multiply both sides by negative making them both positive... b on both sides and your left with ....b=a

Furious Predator rrProfessor Kitchener, Ontario, Canada  im with micheal on this oneedit...never mind....if you do this thing in reverse, it all works out...i have seen this before, but have never been able to figure it out...Shawn

rcsoar4fun rrKey Veteran Boise, Idaho  (aB)(a+b)= A^2 AB + AB  B^2 = A^2  B^2AB+AB=0I give up on Loctite, nothing lasts long enough to vibrate loose anymore.

rcsoar4fun rrKey Veteran Boise, Idaho  Not quite smelling what you are stepping in, to which equation are you apply the squared and the 1I give up on Loctite, nothing lasts long enough to vibrate loose anymore.

michael88997 rrElite Veteran Lewisville,Tx  when i solved this A^2 AB + AB  B^2 = A^2  B^2everything cancells out

helibill rrApprentice London, Ontario, Canada  a^2  b^2 = a^2 ab

Furious Predator rrProfessor Kitchener, Ontario, Canada  umm...thats not what i get...if you move everything over to one side, and make it = 0, you get this...b^2 + ab = 0i solved it two different ways and got the same thing...but i think its still messed up...Shawn

michael88997 rrElite Veteran Lewisville,Tx  yea helibill did what i did only i said it in words lol

umm...thats not what i get...if you move everything over to one side, and make it = 0, you get this...b^2 + ab = 0

Furious Predator rrProfessor Kitchener, Ontario, Canada  ah, bill, your right, i just didn't take mine far enough.i just have the habbit of moving things over to one side....i soemtimes find its easier to visualize things.Shawn

Texas1 rrNovice Tyler, Texas  the problem is your dividing by zero. If a=b then ab=0. You cannot divide a real number by zero.

Rob_T rrElite Veteran ..  This is a classic! The trick is that dividing by zero is not mathematically defined. So, as we know a=b the second line states undefined = undefined. Everything else is just a distraction.

EvoFlight50 rrApprentice Southbury, CT  The problem with his equation is as Texas said. You can't have 0/0. At the first step he set the domain of a and b to 1. If this formula he set up were true for any number other than 1 than his algebra would have been correct. His second step is invalid with a and b having a domain of 1.You'd have 0/0=0/0. Put 0/0 into a calculator and you get an error, it's undefined.

eggmcmuffinplz rrElite Veteran Los Angeles, CA  Well if a doesnt = b, (a=b) = a 1 does not = 2 2+1 doent = 2
