Line 55: :x = 7 and x = -4 where x = 7 is the solution to the problem, and x = -4 is an '''extraneous solution''' because it is not pertinent to the problem. [[User:Tparameter\|Tparameter]] ([[User talk:Tparameter\|talk]]) 17:46, 19 January 2008 (UTC) == My changes == I expanded on this idea a bit, starting with some very simple examples, including discussion of operations that remove solutions, and outlining a more general and (hopefully) more understandable categorization of what operations do what to the solution set.
