How do you find the degree of a Polynomial?
Start by finding the degree of each term in the Polynomial. The degree is all the the exponents added together in a single term. After finding the degree of each term determine which term in the polynomial has the highest degree and that is the degree of the polynomial.
Find the degree of each term. Take the lowest degree out of the terms to determine the degree of the whole polynomial.

You cannot find the degree of a polynomial.
What is a leading coefficient?
The coefficient that is non-existent.
The coefficient of the term with the lowest degree.
The coefficient of the term with the highest degree.
How do you add polynomials?
1)subract
2)multiply
3)divide
1) Rewrite to remove parenthesis.
2)Identify and group like terms.
3)Combine like terms
It is impossible to add polynamials.
How do you subtract polynomials?
Distribute -1 throughout. Then continue with the same procedure for adding.
(3y-4y)
Distribute 1 thoughout. Then do same procedure for substraction.
None of the above.
How to multiply a monomial by a polynomial?
Remove all variables in the polynomial then multiply.
Combining like terms
A single term polynomial.
Distribute the monomial throughout the polynomial.
