This channel is dedicated to helping people of all ages and levels with math. I offer detailed, step by step examples with rules and formulas provided. All videos are also captioned. Message me if you have a suggestion for a video that I currently don't have.
what you meant to ask was: "what is the largest subset of [some field] for which the expression evaluated at every element of that subset is well defined?"
This also could be solved nicely by factoring. The expression x^4-6x^3+33x^2+6x-34 could be expressed as x^4-6x^3+34x^2 - (x^2-6x+34), which you can factor as (x^2-1)(x^2-6x+34). Nice video though, showing RRT
There's many many techniques on how to factor a trinomial, No Fuss Factoring is just the technique that I use. It's a 4-step process. If you send me your email, I can send you an attachment that explains it further, or you can watch some of my other videos that explain it further.
@professorkat ah wonderful. I'm in algebra 2 myself, currently learning polynomials outside of school and systems of equations in school. I thought your video was interesting as it was something new especially that 0 rule or something. do you have any videos to get into trig or precalc?
@@professorkat Like we got a question The way my teacher taught me is that we gotta find the value of x... So when we do that We write Reason And statement E.g Reason Vert.opp Please respond
