Solving this diffEq

1. The problem statement, all variables and given/known data

I have the differential equation:

x' = 2*x^1/2

3. The attempt at a solution

I can see easily that the solution x = t² satisfies the equation, however wolfram tells me the solution is:

1/4 (4 t² + 4 t C + C²)

which also satisfies the solution... I'm wondering how do I solve this diffeq in order to get the solution Mathematic got?
