The following shows the graph for y = x^2 - 12x + 36
+graph%28+300%2C+200%2C+-10%2C+10%2C+-10%2C+20%2C+x%5E2-12x%2B36%29+
The solution to the equation x^2 - 12x + 36 = 0 are the points where the graph cuts the x axis.
In the above fig, we find that the graph touches the x axis at only one point namely 6.
Thus x = 6 is the only solution for the given graph.
