- When you take square root, there are two solutions. In this case, when you take the square root of ((5 - (9/2))^2, you must consider both options. The correct option is -5 + (9/2) which yields 2+2 = 4. One might ask why should I not take +5 - (9/2) as one of the possible square root. The fundamental idea is that 2+2 = 4, no matter what. Hence the only admissible solution of the square root in the present case is -5 + (9/2) and the other one must be rejected.Apr 28, 2015
- math joke ...... haha

its interestingApr 28, 2015 - Fady Aro+3You cannot do that from the begnning where 4 - 9/2 is negative that means you cannot put it under √Apr 28, 2015

- Gotta say, I almost fell for it. Nice try though.May 11, 2015
