An equation if both expressions are equal
Yes, the expression (9x^2 + 81x + 9) is a trinomial. A trinomial is defined as a polynomial with three terms, which in this case are (9x^2), (81x), and (9). Each term consists of a coefficient and a variable raised to a power, fitting the criteria for a trinomial.
To determine which expressions are equivalent, you need to analyze their structure and simplify them if necessary. Equivalent expressions yield the same value for all variable inputs, so you can also substitute specific values to test for equality. If you provide the specific expressions in question, I can help you evaluate their equivalence.

An equation if both expressions are equal
In the same way that you would solve equations because equivalent expressions are in effect equations
That means that the two expressions represent the same number.
If you mean (9x-8y)(9x+8y) then it is 81x^2 minus 64y^2
