Question

Which statement is true about the polynomial

Answer 1

Hello,
Answer B

=-3s^6t²+6st^9-6t^7

Answer 2

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.
