Please graph:$$y=x^2$$
Next, please graph $$y=x^2-6.$$
Note that the 2nd graph looks the same as the first, except that you move the whole graph downward 6 units.

Now estimate where the graph of $$y=x^2-6$$
intercepts the x-axis.  Those two values are your approx. roots.  

The more careful you are in graphing this function, the more accurate your root estimations will be.
