Answer:
a. xy 2
b. 2xy
d. -xy
e. 2x 2y
f. xy
Step-by-step explanation:
Let's begin by explaining that like terms are defined in algebra as terms whose variables with their respective exponents (also called powers) are the same. However the coefficients of each like term do not need to match.
This means like terms are terms that are similar each other.
So, in this case we have terms that are similar because they have the same variables xy, being their exponents equal to 1:
a. xy 2
= 2xy
b. 2xy
d. -xy
e. 2x 2y
=4xy
f. xy
