-6 = -6
9-15 = 4-10
9-15+(25/4) = 4-10+(25/4 ) // adding 25/4 to both sides:
9+(25/4)-15 = 4+(25/4)-10 //Changing the order
//(this is just like : a square + b square - two a b = (a-b)square.)
//Here a = 3, b=5/2 for L.H.S and a =2, b=5/2 for R.H.S.
. ' . (3-5/2)(3-5/2) = (2-5/2)(2-5/2)
3 - 5/2 = 2 - 5/2 //Taking positive square root on both sides
3 = 2

hello sir,
ReplyDeleteI Sent 3=2(proofs) to my friend.she said that some mathematical fallacy in that proofs.I dont know what fallacy in that proofs.pls find and let me know sir.
Hi Alice,
ReplyDelete(3-5/2)(3-5/2) = (2-5/2)(2-5/2)
3 - 5/2 = 2 - 5/2 //Taking positive square root on both sides
This statement is the wrong one.
-2 * -2 = 2 * 2
but that doesn't mean -2 = 2
Hope you got me, let me know if you need more explanation.
