Answer:
Terms: 6x², 6x, -4x, -16
Equivalent terms: 6x, -4x
Coefficients: 6 (twice), -4
Constants: 16
Step-by-step explanation:
A term in an expression is a quantity in that expression. It may include a variable, but it doesn't have to! There are 4 terms in this expression: 6x², 6x, -4x, -16. Remember to put the negative sign in front if the term follows a minus sign.
Equivalent terms have the same variable level. Here, the equivalent terms are 6x and 4x, because they both have x as their variable.
Coefficients appear in front of a variable in a term. There are 3: 6, another 6, and -4.
Constants don't have a variable. There is just one: -16.
