It help factor your answers for the future. Especially when you use factoring, quadratic formula and the like. It's very useful when you reach Freshman Algebra.
Use the quadratic equation: x = [-b +- sqrt(b^2-4ac)]/2a The +- means you get two answers, one by adding, one by subtracting.
No, it must have two answers.
NO!!!! On a graph a quadratic equation becomes a parabolic curve. If this curve intersects the x-axis in two places. then there are two different answers. If the curve just touches the x-axix on one place then there are two answers which both have the same valuer. If the curve does NOT touch the x-axis the there are NO solutions.

This question has multiple answers unless it has a restriction such as 45 and 16.(as if you were factoring)

plug some numbers in for your variable and see if the factored answers match the pre-factored answer
No, expressions cannot have the same value in algebra. They may be assigned to different values and on solving we can get different answers in each case.
Are you sure you typed this correctly? Using normal methods this not factorable -- it si PRIME for the integers. You can use the quadratic formula, but that gives irrational answers for this quadratic.
imaginary numbers occur in the quadratic formula because of the radical symbol, and the possibility of a negative radican and that results in imaginary numbers. I hope this helped!
