Hi 👋

This helps a lot. Wasn’t sure how to approach the exclusions

these are very nice once you practice them.same as functions and graphs they are really lovely once you know what you are doing

There is a mistake rewiting reciprocals with changed signs. But basically it does not matter as we know what cannot be zero.

Brian maed a mistake at last term. x^2-2x-8 factoring out (x+2)*(x-4). so the answer should be x^2+x-6/x(x-4). Excluded values are :0, -1,-2,-3,4.

Easy, just wanted to point out you factored x squared minus 2x-8, and does it matter at the end after you simplified and cancel out all ur factors if you still leaved it in factored form.

is it a typo or you purposely change the sign of 2 in 3:49? you changed the (x+2) to (x-2) when you flip the divisor.

bro ur right

This is the lesson I am in right now in school it is called solving rational expressions and this video really helped me thank you so much😊😊😄😄😄

You are very welcome!!

But too be honest simplifying rationals is easy for a lots of people, but rational functions with the ha, Va, and Sa/oa, all the asymptotes the holes, are easy for me but hard for a lot of people

Does he write on the board backwards so we can see it?

No. He writes on mirrored board.
