Polynomial IdentitiesA polynomial equation that is true for every value of the variable

Ex.



We can prove that a polynomial identity is true by using PEMDAS to simplify one side of equation and confirming is equivalent to the other side.



There are many polynomial identities that we should be familiar with in this course to help us perform mathematical tasks.
