Question

Classify the following into monomials, binomials and trinomials:

$\left(i\right)4y-7x$
$\left(ii\right)y^2$
$\left(iii\right)ab-a-b$
[3 marks]

Answer 1

Monomials: An expression with only one term is called monomial.

Binomial: An expression with two, unlike terms, is called a binomial.

Trinomial: An expression with three, unlike terms, is called a trinomial.

$\left(i\right)4y-7x$ - Binomial
$\left(ii\right)y^2$ - Monomial

$\left(iii\right)ab-a-b$ - Trinomial
