Write your questions and thoughts here!

Precalculus    Polynomials:   A polynomial is one or more monomials put together by addition or subtraction.  Here’s an example of a polynomial:   

2 8 3 1  Each exponent must be a ______________.  The coefficients must be ________________.  Constant Term:  The only term without a variable. (It’s a constant!) Degree: The largest exponent of the variable. Leading Coefficient:  The coefficient of the “degree” term.  Standard Form: The “degree” term is written first and each successive term’s exponent decreases.  Add, Subtract, and Multiply Polynomials: 1.  6 5 6 2
