Question

Which of these is a trinomial

Answer 1

Your answer would be C because a trinomial consists of 3 parts!

Explanation:

Answer 2

`2x^3-7y^3 +14`

Explanation:

Trinomial is a expression that has 3 terms. Now we check the options that has 3 terms.Terms are separated by operators like +,- , x or \

5xy has only one term

`2x-7` has two terms 2x and -7. So it is not a trinomial

`2x^3-7y^3 +14` has three terms 2x^3, -7y^3 and +14. So it is a trinomial.

`2y^2+7y` has two terms, So it is not a trinomial
