Question

Is the expression a monomial? Explain. qs + 5 Yes; it only has one term with a variable. Yes; it only has variables and numbers. No; it is a binomial. No; it is a product.

Answer 1

A monomial has only one term (mono means one). These are examples of monomials:

1) 5xyz,
2) 19m^2 n^2 p^2,
3) x,
4) abc.

qs + 5 has two terms: qs and 5. Then it is a binomial (bi means two).

Therefore, the right answer is: No, it is a binomial.
