Analyze the 4 terms of the polynomial x

Term 1 is x

Since there is no coefficient before our variable, (term does not start with a number), our coefficient is 1

Our variable is the letter which is x

The exponent of our variable is the power that the variable is raised to which is 2

Term 2 is 3y

Our coefficient is the number our term begins which is 3

Our variable is the letter which is y

No exponent exists for this term

Term 3 is 4x

Our coefficient is the number our term begins which is 4

Our variable is the letter which is x

No exponent exists for this term

Term 4 is -13

Our coefficient is the number our term begins which is -13

This term has no variable, so it is a constant

No exponent exists for this term

The degree of the polynomial (highest exponent) for the variable x = 2
