Hi, can anyone help me with this:

y^2=2x+3

x^2+y^2=4

I tried substituting the first line in the second one :

x^2+2x+3=4 => x^2+2x+3-4 = 0 => x^2+2x-1=0

And solve it as a quadratic equation, where x = -1+-sqrt(2)

Am i missing something because, the rezult is not so convinsing.

Thanks a lot. I appreciate it.
