MAT222: Intermediate Algebra Solving Quadratic Equations

In this discussion, you will solve quadratic equations by two main methods: factoring and using the quadratic formula. Please complete the following problems according to your assigned number.

• 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
• Factoring
• Completing the square
• Discriminant

Your initial post should be at least 250 words in length. Support your claims with examples from required material(s) and/or other scholarly resources, and properly cite any references.
