Variable name
Arrow indicates
direction you
should scroll to
view other
solutions.
Press the ] key to view other solutions. Use [ and ]
to scroll between all of the solutions for the equation.
Pressing the
t key at this point returns to the coefficient
input screen.
• Certain coefficients can cause calculation to take more
time.
• Example 1: To solve the equation
x
3
– 2x
2
– x + 2 = 0
(
x =
2, –1, 1)
(Degree?) 3
(a?) 1

(b?) D 2 =
(c?) D 1 =
(d?) 2 =
(x1 = 2) ]
(x2 = –1) ]
(x3 = 1)
• If a result is a complex number, the real part of the first
solution appears first. This is indicated by the “R↔
I”
symbol on the display. Press A r to toggle the display
between the real part and imaginary part of a solution.
•Any time until you input a value for the final coefficient (
c
for a quadratic equation, d for a cubic equation), you can
use the
[ and ] keys to move between coefficients
on the screen and make changes, if you want.
•Note that you cannot input complex numbers for co-
efficients.
Calculation starts and one of the solutions appears as soon
as you input a value for the final coefficient.
