Quadratic and Cubic Equation Solvers

Quadratic (ax 2 + bx + c = 0) or cubic (ax
solved using these functions.
1 Quadratic equation solver (QUAD): b 3 2
2 Cubic equation solver (CUBIC): b 3 3
• If there are more than 2 results, the next solution can be displayed.
• The results obtained by this function may include a margin of error.

• Coefficients can be entered using ordinary arithmetic operations.
• To clear the entered coefficients, press j.
• Press d or u to move line by line.
3 After inputting the last coefficient,
press e to solve the quadratic
equation.
• After solving, press e or j to
return to the coefficient entering display.
You can use @ h to solve the
quadratic equation, regardless of the cursor position.
