This is a great test question

Believe it or not the rational expressions simplifies to 1/2 - kzbin.info/www/bejne/poa3gH1uosiLbZY

This man singlehandedly carried our education

Im in 10th grade and tested this out for myself. Before i thought of simplifying, i just went ahead and got my like denominators. I got x^3 - 11x^2 + 39x - 45. I was stuck with a cubic num. and a cubic denom. I did this before he said to look for simplifications, lol. When I went back and rewrote the math problem, it was smooth sailing! 😎 Thank you so much, Brian!

This man is still doing math tutorials. 1.3 million subscribers on KZbin for a math professor is absolutely insane.

[@Massive_Manchild]

You carried 8th grade math

[@austinvibes2887]

Idk why but every time I see your videos and these equations It makes me miss doing problems and math tests. They were always hard but when I learned how to do equations and get good grades it made me feel accomplished and whatnot. Don't no why but I sorta miss it from time to time lol. Do I secretly like math..... 😅

[@brianmclogan]

Hehehe I won’t tell anyone!

[@riaquiannasteve]

Why does the domain of (5x-4)/(x-5) exclude 3? shouldn't it only be x does not equal 5 because it would be undefined or an asymptote. if x=3 then the value is -2.5

شكرا لحضرتك

Happy to help

Hey! I am from 🇮🇳 . Currently studying in 10th grade. I looked at the question succeeded in solving it . However, it took me 2 min to think about its starting. But I began with the correct step. After finishing its solution, I felt it was a piece of cake 😂 Thanks for bringing such a question.

[@oddi5486]

I watching your videos since 2019

[@Theytook-Hi-awayFromMe]

1 day and 8 hours late 😅 had this type of question on my 4th qt test

[@adityamishra0706]

It's easy top g sir

[@fire4722]

I tried this on a sheet of paper and got 3x-4/x-5 is that correct or not? Edit: after watching the video i can confirm i was right.

[@darrenfalconer3267]

how does -9 x -4 = 13 you really confused me at 4:45

[@pujaraina6698]

He misspoke, he meant that -9x + -3x is -13x

[@lapskunk]

I caught that too, but quickly reqlized he mustve meant +, not x

You're talking too fast and not enunciating your words very well. Hard to follow.

[@brianmclogan]

So sorry

[@cineronsystemlords759]

@@brianmclogan I hope I didn't come across as rude. It was a first impression of the video itself. Your past content has been phenomenal in helping to review for exams. Thank you for making these videos!

[@darrenfalconer3267]

i literally had the same thought watching this, and im english. i thinks its more the excitement, like Brian is super excited to show us the solution. when you understand the maths its probably less of an issue. when you have no idea etc then the speed talking over takes and becomes more stressful to watch.

[@darrenfalconer3267]

i might try watching using the half speed option in player

[@darrenfalconer3267]

ok try it at .75, feels a lot more engaging like hes letting you have a second to think about it
