Polynomials expressions with numbers and
variables involving only addition, subtraction,
and multiplication

• This year well work a great deal with
  polynomials. It will pay to have a look at the
  various polynomial parts, the PPs if you will.
• We have lions and tigers and bears oh, wait.
• We have coefficients, variables, and exponents.
• With those parts, we can ONLY add, subtract, and
  multiply.
• Can someone give an example of a polynomial?
  (Think of the graphs you studied in Algebra I.)

and multiplication

• anxn an-1xn-1 an-2xn-2 an-3xn-3 a1x a0
• This is a general shape for a polynomial looks
  odd, but we can have it make sense.
• Identify the parts coefficient, leading
  coefficient
• variable
• exponent/ degree
• We have two ways to classify polynomials size
  and degree
• monomial,
  binomial, trinomial
• linear, quadratic, cubic, quartic, etc.
