What is the degree of the polynomial? 5x² + 8x³ + 4- 6x² - 3x5

geniusboy [140]

Answer:

The degree of polynomial is 5.

Step-by-step explanation:

I suppose the polynomial is $\displaystyle{5x^2+8x^3+4-6x^2-3x^5}$ . To find the which degree this polynomial is, we consider the highest exponent of the term which is $\displaystyle{3x^5}$ , the 5 is our highest degree of the term and thus, 5 is our highest degree of polynomial.
