Question

Consider each expression. Is the expression a third-degree polynomial? Select Yes or No.
A. 8g^2h - 4gh^2
B. 3x^2 + 5x + 6
C. 8 + 4n - 5n^2 + n^3

Answer 1

Add up the degrees of each term and see!

Answer 2

A = 4
B = 3
C = 6

So: No Yes No? @tkhunny

Answer 3

I see only 3, 2, 1, and 0 for the degree of any term shown. Where did you get 4 and 6?

Answer 4

For A, g^2 and h^2 is 2 + 2 which is 4.
For C, n is the same as n^1 and n^2 and n^3 which is 1 + 2 + 3 which is 6.

Answer 5

No good. Each term separately.

gh^2 ==> 1 (for the g) + 2 (for the h) = 3

Answer 6

Is it yes no yes @tkhunny

Answer 7

There you have it.
