The degree of a term The degree of the entire polynomial is the same as the degree of the term with the largest exponent. Copyright Scott Storla 2015 The degree of a polynomial For each variable term use the exponent to decide on the degree of the term.
Standard Form The terms of the polynomial are written in decreasing order of degree from left to right. Copyright Scott Storla 2015 To write a polynomial in standard form we imagine all operations are addition and all coefficients are explicit, then we use the commutative property to rearrange the terms, last we rewrite all explicit coefficients implicitly.
Standard Form In practice people rearrange the terms of a polynomial “in their head”. Copyright Scott Storla 2015 Write each polynomial in standard form.

Multivariable or “mixed” terms With multivariable terms the degree of the term is the sum of the individual exponents. We don’t actually add the exponents. Copyright Scott Storla 2015
Multivariable or “mixed” terms Copyright Scott Storla 2015 For standard form, terms of equal degree can be written in any order but often decisions are made using alphabetical order.

Terms are like if, in general, they’re counting the same sized unit. Copyright Scott Storla 2015 Only like terms can be added or subtracted.
Like Polynomial Terms Copyright Scott Storla 2015 Polynomial terms in one variable are like if the variable has the same exponent. Constant terms are also considered like.
