· 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
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. Respond to at least two of your classmates’ posts by Day 7.
