Press q(REPT) to edit this problem or continue solving simultaneous equations with three
unknowns. To edit just one of the numbers in the system, arrow to the number to be edited and
press r(EDIT) or highlight the number to be edited and just enter the new number, then press
l.
Press d until the initial Equation Editor screen is displayed. The second mode is Polynomial
(w) and can be used to solve higher-order equations in standard form that are, from the 2
nd
to the
6
th
degree.
2. To solve the equation x
3
– 2x
2
– x + 2 = 0, input the following:
• ww1ln2ln1l2lq
4. The default setting is for real numbers; to change the display to a+bi form, press Lp for the
Equation SET UP menu, highlight Complex Mode, select w(a+bi), d, then q(SOLV).
3. To change the equation to x
3
+ 2x
2
+ 3x + 2 = 0, select q(REPT) and change the b-value to 2,
the c-value to 3 and press q(SOLV).
