Recently on a computational engine called wolframalpha, by accident I put this equation for a solution( I wanted a soln of another eqn). But this mistake is not so anymore, it showed me that almost by every mean mathematics can be manipulated.
Anyways, the engine showed there exists no soln . for this.
I tried this on few others and still got the same. I can't understand this.
-1 and 1 both give 1 when multiplied by itself. No square of a number can be in negative form.
So sqrt(x)=-1 should have the solution as 1.
Can anyone explain this.
Also, I searched this
