I don't know how to answer these questions.

Where did these come from? Is there a context?

 

[JeffM]

Are there values associated with these symbols?

 

[HallsofIvy]

\(\displaystyle (x- v)^2+ w/t- u= x^2- 2xv+ v^2+ w/t- u\)
That's all you can do.

(If you mean \(\displaystyle x^2- 2xv+ v^2+ \frac{w}{t- u}\) then you should write (x- v)^2+ w/(t- u).)

I got this one from one of my students who take UKiset.

Thank you so much

No It' only the variable
