What you’ll learn
Identify parts of expressions.
Key idea
The numerical factor multiplying the variable is its coefficient; a separate constant does not multiply that variable.
An additive constant is not the numerical factor multiplying x; separate terms and factors before labeling them.
Worked example
Classify examples and non-examples for the concept 'Identify parts of expressions'.
In 3x+8, is 8 the coefficient of x? Classify with a factor-based reason.
- The two additive terms are 3x and 8.
- The variable term's factors are 3 and x; its coefficient is 3, while 8 is constant.
Answer: Non-example — the factor multiplying x is 3; 8 is the constant term.
