Question

Answer 1

You are correct trinomial.

Answer 2

Answer:

Trinomial

Step-by-step explanation:

Classify the expression 7x3 + 2x2 − 9x as a monomial, binomial, trinomial, or polynomial.

$7x^3 + 2x^2 - 9x$

An expression with an single term is a monomial , for example 3x^2

An expression with two terms is a binomial, for example 2x+5 has two terms 2x and 5

An expression with three terms is a trinomial . Our given expression has three terms $7x^3, 2x^2 \ and \ -9x$

So it is a trinomial.
