Example Question #251 : Variables

What is the degree of the polynomial?  \(\displaystyle y= -6x+3-5x^4-7+3x^2\)

Possible Answers:

\(\displaystyle 6\)

\(\displaystyle 1\)

\(\displaystyle 4\)

\(\displaystyle 7\)

\(\displaystyle -5\)

Correct answer:

\(\displaystyle 4\)

Explanation:

Reorder the polynomial from the highest to least power.

\(\displaystyle y= -5x^4+3x^2-6x-7+3\)

The degree of the polynomial is the highest power in the polynomial.  The term

\(\displaystyle -5x^4\) exhibits the highest degree of the polynomial.

The degree is \(\displaystyle 4\).
