Try certain physics problems in kinematics without the factoring skill picked up in algebra.
Most of us do not know who "invented" factoring trinomials, many do not even care. Factoring is just one of the axioms that an algebra system establishes. If you really want to know, try searching on Google.
That's what you learn in high school, in a first subject of algebra - things like evaluating expressions, converting them, solving equations, factoring polynomials, etc.
You'll typically use it when solving a quadratic equation - when factoring isn't obvious.
This answer will vary depending on your high school's or college's requirements; but generally, one must have a strong grasp of graphing, systems of equations, and factoring before beginning algebra 2.

trial & error is a general method of problem solving, fixing things, or for obtaining knowledge.
You need to learn it, so you can learn Greatest Common Factor, which you need to reduce fractions.
