Answer 2

Answer:

(a) x²+x+3

Step-by-step explanation:

A trinomial is a polynomial with 3 terms.

Terms are the parts of the polynomials which are separated by “+” or “-” sign.

Let as look at option a: x²+x+3

As we can see, there are 3 parts in this polynomial.

That is, there are 3 terms in this polynomial.

What are polynomials with 3 terms called? TRIMONIALS!

Hence, option a is the answer.

Let us look at the other options. Both option (b) and (c) have 2 terms and hence not trinomials.
