Question

Classify into monomials, binomials or trinomials.

$a^2+b-3b$

Answer 1

Check the terms for type of polynomials.

Given terms are $a^2+b-3b$

Simplify the expression.

$$\begin{gathered} =a^2+b-3b \\ =a^2-2b \end{gathered}$$

After simplification the expression, number of terms are $2$.

Since, we know polynomials which are having two terms are known as binomials.

Hence, given terms are binomials.
