Question

Is this expression a polynomial? If so classify it by its number of terms.x^2+3x-2

Answer 1

are you asking if thats a polynomial?

Answer 2

yes

Answer 3

Best to look up "polynomial" to be certain that you know the definition.

One of the characteristics of a polynomial is that it has several powers of x represented:

x^4, x^2, x, 1 (x is always the base; the exponents are integers equal to 0 or greater than 0.

x+1 is a poly; its highest power of x is the first power, x^1. x+1 has 2 terms.

Devon: Please make certain that you know the term "polynomial" well enough so that you could explain it and give someone else examples of "polynomials." You'll see this word repeatedly in algebra.

If you have looked up "polynomial" and have read the info that Bobo has shared with you, but still have questions, by all means ask those questions here.

Answer 8

ok yes its a polynomial equation

Answer 9

it has no negative terms

Answer 10

OK. Are you satisfied, or do you stillo have questions about this problem?

Actually, you mean, "the given expression in x has no negative EXPONENTS."

Answer 11

and theres 3 terms which would make it a trinomial... am i correct?

Answer 12

tERMS of a polynomical CAN certainly be negative, but not the exponents of the variable, x.

Yes, it's a trinomial. Very good.
