Practical use of polynomial equations

[Roseluvtx]

I can factor and divide polynomial equations, wasn't sure what they mean by practical use of polynomial equations?

I...wasn't sure what they mean by practical use of polynomial equations?

Who is "they"? What did "they" ask? (We weren't part of whatever conversion you had with whoever "they" was.)

Please reply with clarification. Thank you.
