Algebra I Help: Determining the Restricted Values for a Rational Expression II

In this video, we learn how to determine where a rational expression is undefined. The values that make the denominator equal to zero for a rational expression are known as restricted values. We find these values by setting our denominator equal to zero, and solving the resulting equation. The solutions are the restricted values, since they result in a denominator of zero when replaced for the variable(s).

Way more helpful than what my school provides (online math classes are not easy, lemme tell you)!

Looking for an answer for my son and I had it within the first 49 seconds.
Thank you.
My Son thanks you.

My man draws better with a mouse than I do with an actual pencil

THANKYOU I have literally been trying to find this for the past few hours, struggling with my math because of this exact problem

[imnotacat]

What is this point of this.? Are we just trying to find what isn't the answer.?
Why not just solve the equation.?

I know this was 9 years ago, but you saved me

Thanks for the videos, they're a huge help

[seraphim]

ohhh thank you very much this lesson is really hard to understand but know i understand it again thank you

[IDK-lzkh]

Is this for rational Algebraic expression???//

[popcat]

This is so useful bc i'm still high school and didn't understand this

Got it! so the point is ("Do NOT get a Denominator to equal zero, because if it does then that's when your in trouble...) Makes Sense








Someone please let me know if I am right or wrong.

My HM: (3/X)=(15/(8x))+3
It it asking that I find the restrictions on the variable but I already know that x=(3/8) so why find the restrictions.?

[typicalpatatas]

can you please answer my assignment asap please as in now. i'm having a head ache because of this lesson

[LibreEspiritu]

so how do you answer Not factorable or undefinable ??

[britt]

So basically, the x values are the restrictions? It seems the opposite of what you're left with.

That sounds like a South Louisiana accent! Am I right? Either way, Thanks for the help.

Omg thank you for this video so helped me understand it, everything makes sense now lmao it really does tho
