What does it mean to write a polynomial in descending order?

Back

Writing a polynomial in descending order means arranging the terms from the highest degree to the lowest degree. For example, 2x^3 + 9x^2 + 5x + 27 is in descending order.

How do you classify a polynomial with two terms?

Back

A polynomial with two terms is called a binomial. For example, 3x^2 - 5 is a binomial.

What is the degree of a polynomial?

Back

The degree of a polynomial is the highest exponent of the variable in the expression. For example, in the polynomial 4x^3 + 2x^2 + 5, the degree is 3.
