Question

Which of the following is a trinomial? c2 + c + 6 c2 − 16 −8c c3 + 4c2 − 12c + 7

Answer 1

Trinomial is defined as a polynomial with three terms separated by a operation (+,-). 

c² + c + 6     AND     c² − 16 −8c    are trinomials.  

c² + c + 6    
1st term: c²
2nd term: c
3rd term: 6

c² − 16 − 8c
1st term: c²
2nd term: 16
3rd term: 8c

When there is only one term it is identified as monomial; two terms is identified as binomial; polynomial means many terms.

Answer 2

Here is your answer:

Remember this monomials have one term, binomials have two terms and trinomial have three terms. So in this case you are looking for a equation with three terms which would be "$c^2 + c + 6$."

This equation has three terms c^2, c, and 6 which makes it a trinomial.

Hope this helps!
