EQUATION

Press D to return to the previous screen, 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 Equation Editor screen is displayed. The second mode is W Polynomial and can be used to solve high-order equations in standard form that are, from the 2nd to the 6th degree.

2.To solve the equation x3 – 2x2 – x + 2 = 0, input the following:

3.To change the equation to x3 + 2x2 + 3x + 2 = 0, select Q (REPT) and change the b-value to 2, the c-value to 3 and press Q (SOLV).

4. The default setting is for real numbers; to change the display to a+bi form, press LP for the Polynomial SET UP menu, select W (a+bi), D, then Q (SOLV).

Solver is the third function Eand allows you to determine the value of any variable in a formula or equation. You can input any formula exactly as it appears using Afor any variables. In this example, we will solve a linear equation and a formula.
