What are the typical steps in Factoring an equation? For example x^2 - 121

First, you begin by preparing the problem to be solved by setting up 2 sets of parenthesis because the problem begins with x squared. An average problem will be set up as Ax^2+Bx-C being that there is an absence of B(x), we assume that it is 0. Now, what will multiply to be -121 but add up to be 0? Negative 11 x positive 11 multiply to be -121 and add to be 0. so the answer will be (x - 11) (x + 11).
