Question

State if the given pairs of terms are like or unlike.

$-25xy,-25yz$.

Answer 1

Given, terms are $-25xy,-25yz$

Here,

$$\begin{gathered} \Rightarrow -25xy=-25\times x\times y \\ \Rightarrow -25yz=-25\times y\times z \end{gathered}$$

Since we know that the terms of algebraic expression which contain the same algebraic factors are called like terms.

Hence, both are not having same algebraic factors and they are unlike terms.
