I think you made a minor mistake with the first one when you multiply the negative with x and +2 wouldn’t the end result be x+1-x-2?

@nihan420

Yeah, as x+1-(x+2) is the same as x+1-1(x+2) and if you take away the parentheses + becomes - , resulting into x+1-x-2

Hello Brian, thanks a lot for making this video. When you factored out -2x^2 + 3x - 1 with the negative sign, you forgot to write the ^2 on 2x. You wrote -(2x + 3x -1). It’s -(2x^2+3x-1).

You explain the steps a lot better than my professor. Everything that is confusing, you make it seem really easy to understand.

Gosh, I couldn't help but watch this. I need to learn to solve these rational equations and inequalities for my upcoming midterm.

I'm convinced it's better to just multiply the denominators and simplify from there. LCD just isn't worth it when it comes to complex rational expressions. You'll get the same end result (remember to simplify) and suffer less of a headache.

Thanks a lot!

Thank you! Because i have homework about add and sub and it worked

Did anyone else notice in the first one he didnt end up changing the +2 to a -2 immediately after point it out lo. I think the answer is -1/x-1 I'm sure that can be really confusing to someone trying to understand and they don't understand what to do from the very first example.

Thank you habibi

I grew up watching this guy lol

So do you have to factor out the numerator for the final answer if possible or is it okay if you don't?

Can you try solving subtraction of function with different denominators sign

What if you have a rational expression with no variables in the denominator like this one 3x/8 +y/8? in this case I have a common denominator already however am uncertain how to solve.

God damn,I am a filipino but I understand you more than my filipino teacher.

Hello there, I am bit confused with 3rd Question - After you found common denominator x + 1, x +2, why did you not multiply Numerator 5x - 1 with x + 2, like you did on Right side of equation with 2x ?

@matthewosto8851

Жыл бұрын

because that one already had (x+1) (x+2) rather the rational expression with 2x only had one of them so you need to have both.

@julietgallant6838

11 ай бұрын

Because what it needs is only x+ 1 on the right side to get a common denominator. The left has a complete set (x+2) (x+1) so, you can leave it as it is.
