Question

The degree of the polynomial $8z^5-9z^4+12z^2$ is:

• A. 2
• B. 3
• C. 4
• D. 5

Answer 1

The correct option is D 5

The degree of a polynomial in one variable is the greatest of the powers (exponents) of its various terms:

The exponent of the term $8z^5$ = 5
The exponent of the term $9z^4$ = 4
The exponent of the term $12z^2$ = 2
Since the greatest exponent is 5,
The degree of the polynomial $8z^5-9z^4+12z^2$ is:5
