For any quadratic equation the axis of symmetry will be this: 

x=-b/2a 

For example: 

x^2+6x+13 A=1 B=6 C=13 
Axis of Symmetry equation x=-b/2a 
x=-6/2(1) 
x=-3 

So the axis of symmetry for this equation would be a line at x= negative 3. Hope this helps. Post with additional details if it still doesn't make sense!!!
