document.write( "Question 361107: Hello! I am working on quadratic equations this week, in my Algebra class (section 11.4, #7). At the current moment I am stumped and totally confused on this one problem we are required to do. Apart of the requirements for completing the assignment is to show every single step on how I got to my answer. I wasn't sure if anyone could help me, but I thought I would post to see who's the master at these type of equations. Thank you so much in advance for all your help!\r
