You would use the pythagorean theorem to solve this equation: a^2 + b^2 = c^2
12^2 + b^2 = 20^2
b^2 = 16
x = 16

Answer:
See the attached graph from which we obtain x = 3 as the only solution for the given equation.
Step-by-step explanation:
Notice that the equation is the same equation as when y = 0 in the function , since when y=0 we have:
Then what we need to find is for which values of "x" in the graph of y = x^2-6x+9, the graph touches or crosses the x-axis (that is when y=0)
We graph the given function in the x-y coordinate system and find where it renders zero for "y" (see attached graph).
We see that there is only one point of contact with the x-axis at x = 3
