Answer:
7x^5+2x^2+6
Step-by-step explanation:
7x^5+2x^2+6
6x^7-x^4+5
6x^5+x^4+7
7x^6-6x^4+5
5th degree polynomial means the the term with highest degree has degree 5.
7x^5+2x^2+6
6x^7-x^4+5
6x^5+x^4+7
7x^6-6x^4+5
Leading coefficient is the coefficient of the term with highest degree.
Constant is the number with no variable.
7x^5+2x^2+6
