P.3 Classifying, Adding, and Subtracting Polynomials

Number Talk

There is only one number in the
entire world that works when
plugged into the following
equation:

What is it?

Can you disprove the above
statement?

Important Definitions

Polynomial- a mathematical expression with multiple terms

Term- an expression made up of coefficients, variables, and exponents (no +/-
signs)

Coefficient- the number before the variable

Degree- the highest exponent number of the polynomial

Classifying Polynomials

By Degree:

●0- Constant

●1- Linear

●2- Quadratic

●3- Cubic

By Term:

●1- Monomial

●2- Binomial

●3- Trinomial

Adding/Subtracting Polynomials

We add/subtract polynomials by adding/subtracting the coefficient of
like terms:

A “like term” is classified by two pieces of criteria:

●Same variable(s)

●Same degree
