3x²
This term represents a monomial expression. Mono- means one. This term is by itself. It has no other term added or subtracted to it.
The coefficient of this term is 3 because it is the number that the variable is connected to.
There are no constants because this is a monomial expression.
4w⁹ -2w⁹
= (4-2)w⁹ . . . . . distributive property, or "collecting terms"
= 2w⁹
_____
In plain text, a caret (^) is used to identify an exponent. w⁹ = w^9. If the exponent has any arithmetic, you need parentheses around it. w^(8+1)
