4-4Complex Number Solution (Example: x3 + 2x2 + 3x + 2 = 0)Complex Mode: Real (page 1-33)Complex Mode: a + biComplex Mode: r∠θ• Internal calculations are performed using a 15-digit mantissa, but results are displayedusing a 10-digit mantissa and a 2-digit exponent.• It may take considerable time for the calculation result of a high-order equation of 3rd degreeor higher to appear on the display.• An error occurs if the calculator is unable to find a solution.• High-order equation calculations may not produce accurate results when the equation hasmultiple solutions.• After calculation is complete, you can press 1(REPEAT), change coefficient values, andthen re-calculate.3. Solve CalculationsThe Solve calculation mode lets you determine the value of any variable in a formula withouthaving to solve the equation.Important!• You can input either an upper-case X (a+(X)) or lower-case x (v) for variable X.Both “X” and “x” refer to the same variable.1. From the Main Menu, enter the Equation mode.2. Select the SOLVER mode, and input the equation as it is written.• If you do not input an equals sign, the calculator assumes that the expression is to the leftof the equals sign, and there is a zero to the right.• An error occurs if you input more than one equals sign.
