What is a polynomial?

Algebra: A field of math that works with unknown numbers (represented with a
letter ex: x)

How do we handle something like:

This is called an Algebraic Expression, which is any number made of numbers
and unknowns

Linear: When a graph of a relation is a straight line.
Direct Variation: has an equation of the y=mx, meaning that the line crosses the yaxis
at 0.
