You can put this solution on YOUR website!
make a table of x and y values, plug in any value for x and solve for y (ie y=x%5E2-12x%2B36) that will give you points to plot the graph. you need about 5 or so points. Then plot it and see where the graph crosses x axis. next plug those points in to see if left side equals right side.
+graph%28+300%2C+200%2C+-2%2C+10%2C+-2%2C+40%2C+x%5E2-12x%2B36%29+
from the graph you can tell that the solution is at x=6 so plug that into your equation
x%5E2-12x=-36
6%5E2-12%2A6=-36
36-72=-36
-36=-36 left side equals right side so solution is correct
