: (–b + (d) )/(2a) → m
calculates one root and stores it as m
: (–b – (d))/(2a) → n
calculates the other root and stores it as n
: If d < 0 Then
tests to see if the discriminant is negative;
: Goto Label1
if the discriminant is negative, jumps to the line Label l below
: Endlf
if the discriminant is not negative, continues on to the next line
: If d = 0 Then
tests to see if the discriminant is zero;
: Goto Label2
if the discriminant is zero, jumps to the line Label 2 below
: Endlf
if the discriminant is not zero, continues on to the next line
: Disp "Two real roots", m, n
displays the message "Two real roots" and both roots
: Stop
stops program execution
: Lbl Label1
