Question

Which of the following is not a trinomial with $5p,3q$, and $7$ as terms?

• A. $5p–3q+7$
• B. $5p+3q–7$
• C. $5p–3q–7$
• D. $5p\times 3q\times 7$

Answer 1

The correct option is D $5p\times 3q\times 7$

A trinomial is an algebraic expression that has three non-zero terms.
The algebraic expressions $5p+3q–7,5p–3q–7$ and $5p–3q+7$ are trinomials.
$5p\times 3q\times 7=105pq$ is not a trinomial. It is a monomial.
