The two terms 3z^2 and -2z^2 are unlike or like terms?

They would be like terms because as you can see, there is only 1 difference. In the expression 3z^2 and 2z^2 the only difference is that the first two numbers are different.

I think this would be unlike. It doesn't matter if the numbers are similar to one another or not, as long as the numbers match. The negative 2 would make this an unlike term..
