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
Solution
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.
