Answer
The solutions to the given equation are $x=0$ and $x=4$.
Work Step by Step
The equation involves only the variable x.
The solution to the equation will be the x-coordinates of the points where the graph of $y=x^2-4x$ crosses the x-axis. These are the x-intercepts of the parabola.
(Refer to the graph in the attached image below)
Thus, the solutions to the equation are $x=0$ and $x=4$
