Question

HELP PLEASE
Choose the correct classification of 5x + 2x2 − 8 by number of terms and by degree.

Third degree polynomial

Fourth degree trinomial

Second degree trinomial

Sixth degree polynomial

Answer 1

Well, the degree is the greatest index of the variable of any term in the expression - so what's the degree for this?

Answer 2

rewrite the polynomial

2x^2 + 5x - 8

the degree is determined by the highest power of the pronumeral

Answer 3

...? umm so the 3rd degree?

Answer 4

Nope - what;s the degree for this polynomial? i see that there's an x raised to the second power. See any terms with a greater power?

Answer 5

umm no...i dont.

Answer 6

So '2' is the highest power - agree?

Answer 7

yes.

Answer 8

Now if you read what Campbell or I wrote above - the highest power of any term is called the degree.
So if '2' is the highest power of any term in this case - what would be the degree?

Answer 9

2nd..?

Answer 10

Answer 12

No worries!
