Calculus Separable Differential Equation Problem that I m stuck on, Help?!?

The problem is to solve dy/dx= (y-1)(y+1) if the solution passes through the point (x,y)=(1,0). I have found the Implicit solution of what I think is ln(y-1)^.5-ln(y+1)^.5=Ce^t. But I cant find a solution so that y(x)= and there is no c, its solved for. Any ideas??
