Question

Combine Like terms : - 3xy - 3xy - 2xy

Answer 1

We have to combine the like terms in this expression.

If we look at the 3 terms, all of them are multiplying the same factor xy, so we can write:

`\begin{gathered} -3\cdot xy-3\cdot xy-2\cdot xy \\ (-3-3-2)\cdot xy \\ -8xy \end{gathered}`

Then, the equivalent expression after combining the like terms is -8xy.
