Find the value of x where f(x)= x^2-3(x+2)^(1/2) has its absolute minimum.

I know I'm supposed to take the derivative and set that equal to zero to find the critical points. However, I keep getting stuck and can't seem to find the critical points because I get lost in the math.

Thank you for any help!
