Essential Notes
Polynomial: One term or the
sum/difference of two or more terms.
To be a polynomial:
• Variable Bases
• Whole number exponents
• Real number coefficients
The degree of a polynomial is the
same as the largest exponent.
We write polynomials in standard
form which means write exponents
in descending order from left to
right.
When in standard form, the
in the front.
