Question

Classify the following into monomials, binomials, and trinomials:
$\left(i\right)7mn$
$\left(ii\right)z^2+z$
$\left(iii\right)1+x+x^2$
[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.
$\left(i\right)7mn$ = monomial [ 1 mark ]

$\left(ii\right)z^2+z$ = Binomial [ 1 mark ]

$\left(iii\right)1+x+x^2$ = Trinomial [ 1 mark ]
