Answer:
It has 3 terms and a degree of 9.
Step-by-step explanation:
\(5s^6t^2 + 6st^9 - 8s^6t^2 - 6t^7\)
before finding the degree we simplify the given polynomial
we combine like terms
the terms that has same variable with exponents are like terms
5s^6t^2 - 8s^6t^2=-3s^6t^2
\(-3s^6t^2 + 6st^9 - 6t^7\)
Simplified polynomial has only 3 terms
Degree of s^6t^2 is 8
degree of st^9 is 9
degree of t^7 is 7
largest degree is 9
So degree of this polynomial is 9
It has 3 terms and a degree of 9.
