Question

Identify the monomials, binomials and trinomials among the following.

${\mathrm{m}}^2+{\mathrm{n}}^2-2\mathrm{mnp}$

Answer 1

In the expression ${\mathrm{m}}^2+{\mathrm{n}}^2-2\mathrm{mnp}$ there are three terms $m^2,n^2$ and $-2mnp$.

The expression which has only three terms is called trinomial.

Hence, the expression ${\mathrm{m}}^2+{\mathrm{n}}^2-2\mathrm{mnp}$ is trinomial.
