Solving Quadratic Equations Discussion

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.

  Use FACTORING to solve: Use the QUADRATIC FORMULA to solve:
  x2 – x – 6 = 0 −8, 2

· 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.
