Step 2: In a posting to the Discussion Board in Falcon Online, explain thesolution method you chose for each equation and why you chose it. Refer to each equation by letter when stating the solution method. It is not necessary topost the solutions and answers. The posting should be written with complete sentences and proper grammar. The following explanation is not an acceptablepart of the posting: “This was the last method left.”
