Hi. This isn't for any sort of homework. I've run into a deadend where I have a situation like this where I need to solve for "a": a(a+b+c) =d You'd think it would be easy but I can't seem to get "a" by itself. It always end up on both sides of the equation at best which is starting to make me think it's somehow recursive. I know how to solve it if it didn't have the "c" by using the quadratic equation but not sure in this situation. Thanks so much!!
