In the program editor, input the formula: prompt A, B, C; then calculate the discriminant (B² - 4AC) and use √ to find the square root. Finally, display the results for the two roots using Disp for the formulas: (-B + √D)/(2A) and (-B - √D)/(2A). Make sure to include appropriate prompts for user input.
