Is 2x an expression?
This type of expression has only one term , for example, 2x, 5x 2 ,3xy, etc. An algebraic expression having two, unlike terms, for example, 5y + 8, y+5, 6y 3 + 4, etc.
What is 3x 2 as an expression?
Answer: In each of the terms 3x 2 and 7x, x is a variable, and in both terms, we are multiplying a number by the variable. In the first term, 3x 2, 3 is being multiplied by the variable, so 3 is a coefficient. In the second term, 7x, 7 is being multiplied by the variable, so 7 is a coefficient.
What are the terms in an expression?
Term: Each expression is made up of terms . A term can be a signed number, a variable, or a constant multiplied by a variable or variables. Factor: Something which is multiplied by something else. A factor can be a number, variable, term, or a longer expression.

How many terms are in an expression?
A Term is either a single number or a variable, or numbers and variables multiplied together. So, now we can say things like “that expression has only two terms “, or “the second term is a constant”, or even “are you sure the coefficient is really 4?”
Which is an example of an algebraic expression?
Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.
