When I write sqrt(x) I only get the graph on the positive side. Shouldn't this equation give two answers for x?(Since x^2 = (-x)^2)
it's by convention that 'sqrt' gives only the positive root. If you write it in symbols or draw the graph of y=sqrt(x) it is too, so not only in this GG software.
As Chris says sqrt(x) is a function so y=x^2 has these two separate solutions
If that wasn't the case you wouldn't write the “±” symbol in https://en.wikipedia.org/wi...
