Convert it into the y=a(x-h)+k form and the values of h and k are your vertex.
You can convert by completing the square method.

lol have fun on this ....
//You need to factorise the two quadratics and divide where possible
x^2 + 3x + 2 = (x+2)(x+1)
x^2 - 4 = (x+2)(x-2)
y = (x+2)(x+1)/(x+2)(x-2)
y = (x+1)/(x-2)
