82     on p. 637  For the factoring problem, be        sure you show all steps to the factoring and solving. Show a check of        your solutions back into the original equation. For the Quadratic Formula        problem, be sure that you use readable notation while you are working        the computational steps. Refer to Inserting Math        Symbols for guidance with        formatting. Present your final solutions        as decimal approximations carried out to the third decimal place. Due to        the nature of these solutions, no check is required. Incorporate the following        four math vocabulary words into your discussion. Use bold font to        emphasize the words in your writing (Do not write definitions for the        words; use them appropriately in sentences describing your math work.):         Quadratic formula  Factoring  Completing the square  Discriminant
