1. w2 − 2w = 15 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. • 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.): o Quadratic formula o Factoring o Completing the square o Discriminant Please write out the steps.
