4. TERMS 2x + 8 Has 2 terms 2x + 8 Has 2 terms An expression with ANY NUMBER of terms is called a ___________________ are separated by + or – signs

5. Monomial– a single TERM containing an integer, variable, or combination Examples:________________________________________ Requirements: Monomials must have whole number exponents Monomials don’t have variables in the denominator (if they are a fraction) Monomials don’t have variable exponents.

6. Two terms ______________________ Examples: ______________________________ Binomial Three terms ______________________ Examples: _____________________________________________ Trinomial

7. Standard Form: the degrees of the terms decrease from left to right. If two monomials have the same degree, they go alphabetically –2 + 7x – 2 – 2x 5 + 7x Things to Remember: Variables ALWAYS have an exponent Combine like terms Simplify numbers x 2 + y 3 − yz 2 x – xy 2 − 4 3 + 3 2 x Degree– The sum of the exponents of a monomial Examples:________________________________________

8. Practice: Find the degree of the polynomial Standard formDegree A polynomial is defined by the monomial with the highest degree xy 2 + z 4 x 5 - y 3 + 2 6 7 2 x 4 -y
