An equation that expresses a relationship between two or more variables, such as Upper H equals nine tenths left parenthesis 220 minus a right parenthesis , is called Formula.

A formula is an equation that expresses a relationship between two or more variables.

The process of finding formulas to describe real-world phenomena is called mathematical modeling.

Such equations, together with the meaning assigned to the variables, are called mathematical models.

when studying polynomials, you often hear the terms zeros, roots, factors and x x the multiplicity of a zero is important because it tells us how the graph of the let's look at the graph of a function that has the same zeros
