Question

Identify the like terms among the following:

7x, 5y, −8x, 12y, 6z, z, −12x, −9y, 11z.

Answer 1

• Here, we need to group up like terms together. If we observe carefully, we can observe that there are three literal coefficients, namely x, y, and z.

• We can group up the required terms which have the same literal part but different numerical coefficients.

• Let’s take the first literal, x.

The like terms related to x are: 7x, -8x, and -12x.

• Considering the literal y, we have:

5y, 12y, and -9y.

• Considering the literal z, we have:

z, 6z, and 11z.
