Question

1. what type of term is $5x^2$ in the expression $x + 5x^2 - 3$?

a. constant term
b. variable term
c. isolated term
d. numerical term

Explanation:

A variable term contains a variable (a symbol representing an unknown value). The term \(5x^2\) includes the variable \(x\), so it is a variable term. Constant/numerical terms have no variables (e.g., -3), and "isolated term" is not a standard classification for such expressions.

Answer:

b. Variable term
