Question

Simplify the following by combining the like terms and then write whether the expression is a monomial, a binomial or a trinomial.

p³q²r + pq²r³ + 3p²qr² – 9p²qr²

Options

• Monomial

• Binomial

• Trinomial

Answer 1

Trinomial

Explanation:

We have, p³q²r + pq²r³ + 3p²qr² – 9p²qr²

By combining the like terms,

= p³q²r + pq²r³+ 3p²qr² – 9p²qr²

= p³q²r + pq²r³ – 6p²qr²

The expression contains three terms. So, it is trinomial.
