In this discussion, you will solve quadratic equations by two main methods: factoring and using the quadratic formula View the example to complete this discussion.
- 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 the Inserting Math Symbols handout 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
- Completing the square
Use FACTORING to solve:
Use the QUADRATIC FORMULA to solve:
|25x – x3 = 0|
3x2 + x – 2 = 0
