develop your own real world equation using words for the variables. Then, translate your equation into polynomials and share both versions of the equation

OK, this is rather general!!! Here's a simple response:

If Jim is 4 years older than twice Mary's age

Let Jim's age = y

Let Mary's age = x

y=2x+4

If you want X^2, come up with a area problem? E.g., the area of a square :

A (area) = s(side)^2

I'm sure you can take it from here?
