How to identify Degree and Leading Coefficient of a polynomial

The video tutorial explains how to write polynomial expressions in descending order of powers. It highlights the importance of identifying the highest power and arranging terms accordingly. The tutorial also covers how to determine the degree and leading coefficient of a polynomial. A correction is made regarding the leading coefficient, emphasizing the need for accuracy in mathematical expressions.

What is the correct order to arrange the terms of a polynomial?

• In any random order

• In alphabetical order

• From the highest to the lowest power

• From the lowest to the highest power

Which term represents the degree of the polynomial 2X^9 + X^7 - 13X^2?

• X^9
