currently the second text object is highlighted and a text object can't be plotted.
Highlight the polynomial by clicking on it (this makes the algebra window the active
window), then make the 2D-plot window active again by clicking its Title Bar.
There are several techniques to make a different window active:
From the algebra window use the Command Toolbar's
the 2D-plot window use the Command Toolbar's
Click on the window you want to make active. This method, however, must be used with
care: Clicking on an algebra window with the left mouse button is likely to alter the
highlighting, clicking on a 2D-plot window with the left mouse button is likely to move the
graphics cross, this might have unexpected effects. Therefore, it is better to click with the
right mouse button to change windows, or to click, with any mouse button, into the window's
Title Bar.
