Question

Please help!! Which of the following terms are like terms?

a) x and x^2

b) 4x and 3xy

c) 3a and 3x

d) 2xy and -6xy

Answer 1

I think the answer is D

Answer 2

Hey kiddo.

The answer is d) 2xy and -6xy

The "terms" would be the variables (the letters) 
We know that they are (a)like terms because they have the same variables such as: xy
