You need to learn it, so you can learn Greatest Common Factor, which you need to reduce fractions.
Introduces the student to the fundamental concepts of algebra. Topics include the following types of expressions and equations: linear, rational, and radical. Other topics covered include exponents, functions and factoring
Trial and error is a fundamental method of problem solving. It is characterized by repeated varied attempts which are continued until success.SIMPLIFYING FRACTIONSsimplifying fractionsWhen you try to factor a polynomial the most taught method is trial and error. My manipulating the factors you see which terms and coefficients answer the question.
I'm going to differ on many thoughts. I believe that geometry is MUCH easier than Algebra 1 - especially the 2nd semester of algebra 1 which a good chunk of time was spent on factoring and quadratic equations. The Algebra used in geometry is fairly basic - lots of 1 and 2 step equations. By the second semester you will get into some more complicated algorthims when dealing with area and surface area but that is about as difficult as it will get. I bet you'll feel that your algebra skills increase after looking at things geometrically.
No. Trial and error is the most inefficient way for factoring.
Yes
because we can find the unown

Try certain physics problems in kinematics without the factoring skill picked up in algebra.
there was trial and error? haha
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.
Algebra, Geometry, statistics, factoring
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.
