The top part of that image is the equation itself. The bottom part is a graph of the equation, which, as you can see, is exactly the same. To be fair, this equation cheats a little bit.

The roots of the equation y = x 2 x 4 are the x-coordinates where the graph crosses the x-axis, which can be read from the graph: x = 1.6 and x = 2.6 (1 dp).
