Enter the text: "Next we compute the polynomial's zeros by applying the SOLVE function
to the corresponding polynomial equation."
Generate the corresponding polynomial equation.
Highlight the polynomial #1, move focus into the entry line with (F2) (which is the hot key
for authoring expressions), then auto-paste a copy of the polynomial using the hot key (F3).
(F2) may become your most frequently used hot key.
Replace y with 0 then conclude the input with (¢).
