What is the term for an algebraic expression that consists of two or more terms separated by addition or subtraction?

• A. Polynomial
• B. Monomial
• C. Irrational Number
• D. Real Number

Answer: (A)

When an algebraic expression has two or more terms separated by plus or minus signs, it’s called a polynomial. A polynomial is built as a sum of monomials, where each monomial is a single term like 3x^2 or -7. So expressions such as 3x^2 - 5x + 7 fit the description because they contain multiple terms. In contrast, a monomial has only one term, and terms like irrational numbers or real numbers describe values rather than the way an expression is formed.
