Simplify a rational expression by factoring in two different ways

[@thenamelessking6896]

At 8:42 is it necessary to point out that x =/= 3/2 or is it assumed since it's in the function. Do you only need to state x =/= 2 because it's a gap that resulted from canceling out the numerator and denominator or is it necessary to state both restrictions?

It's always good to put them down during a test, as you won't risk losing points. I like to think that when you are doing these problems with 'X', you are giving the solution to someone who doesn't know anything other than numbers. If they see that they can't plug in certain numbers, despite it being shown in the problem, it would help them know what numbers to plug into the equation. It's not that necessary, but it's always nice to put it there.

Me, a college sophomore getting a refresher on factoring with a middle school class🥲

[@atinyworldofdimples9865]

Ha college freshman year here, right there with ya, it sucks we forget all this by the time we get to college

[@moneyonmymind4617]

im gonna be a college freshman and I'm studying for a placement test legit using ALL his videos he's the best

[@luckycharm895]

okay like i understand the whole thing but i would like to know if their is a shortcut to finding whic 2 numbers give us that specific sum or product

[@theballeraryan1254]

you made a mistake you changed +6 to -7 in the bottom equation

[@sc7187]

For the first equation, why did you chang the -4 to a 4? but the second one you left -7? I'm so confused!

[@colourlessfool5107]

Just wondering if there is a faster way

You're a legend!

Is it weird that I am in 8th grade but learning trigonometry?

Lol you make me laugh bro 😂

[@973pop]

Watching this just confused me more nd irritated me
