-4m + 2n + 3n - 2m.

identify the terms, like terms, coefficients and constants

Like terms: -4m and -2m 2n and 3n Coefficients: -4, 2, 3, and -2 Constants: Non Variables: M and N

Step-by-step explanation:

Terms are: -4m, 2n, 3n, -2m

Like terms are: -4m and -2m

                              and

                           2n and 3n

Coefficients are: -4, 2, 3, -2  

Constants are: There are no constants in this expression

Step-by-step explanation:

Terms are = -4m, 2n, 3n, -2m because terms are expressions that are separated by mathematical symbols. ( Division, multiplication, addition, subtraction )

Like terms are = -4m and -2m because they are both expressions with the same variable ( m )  

Coefficients are = -4, 2, 3, -2  because coefficients are the numbers in front of a variable

Constants are = There are no constants in this expression because constants are terms without a variable. These values don't change.

Hope this helps!
