Final answer:
Without the original equation, it's not possible to tell which of the potential answers is a valid solution. However, it has been given an illustrative example of a solution process.
Step-by-step explanation:
Unfortunately, the original question lacks a distinct equation for us to solve. The options given, a. x=-6 b. x=-4 c. x=2 d. x=4, appear to be potential solutions to an equation, but without the equation itself, it’s impossible to determine the other solution(s). However, take an equation as an example, x^2+2x-8=0. This quadratic equation can factored into (x-2)(x+4)=0, we can conclude that the solutions would be x=2 and x=-4.
