This is probably a silly question but I'll ask anyway. I know that terms in mathematics are numbers or variables or some combination of numbers/variables multiplied by each other. They are combined through addition and subtraction. So, in the expression $3a + 2b - 4$, $3a$ is a term, $2b$ is a term and $4$ is a term. But what about an expression or an equation where a binomial (or trinomial, etc.) is embedded within a product or a rational expression? So, for instance–in the expression
$$2x(x+1) + 4x^2 - 2x$$
Is $x + 1$ considered a term? Do we consider $2x(x+1)$ a term? Or would I just say $2x$, $x$, $1$, $4x^2$ and $2x$ are terms? Please help to clarify!
