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
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?
