Let’s solve this step by step.
---
Part A: Matching Type
We match each definition in Column A with the correct term in Column B.
1.
A term with no variables → This is a
Constant.
(Example: 5, -3, 0 — these are constants because they don’t have letters like x or y.)
2.
Numbers attached to variables in a term → This is a
Coefficient.
(Example: In 4x, the number 4 is the coefficient.)
3.
A part of an algebraic expression separated by “+” or “-” signs → This is a
Term.
(Example: In 3x + 2y – 7, there are three terms: 3x, 2y, and -7.)
4.
A polynomial with two terms → This is a
Binomial.
(Example: x + 5, or 2a – 3b — both have exactly two terms.)
5.
Terms with the same variable(s) of the same degree → These are
Like terms.
(Example: 3x² and 5x² are like terms; but 3x² and 3x are not.)
So matches:
1 → Constant
2 → Coefficient
3 → Term
4 → Binomial
5 → Like terms

Part B: Polynomial or Not?
Remember: A
polynomial must have:
- Only non-negative integer exponents (no negative or fractional exponents)
- No variables in denominators
- No variables under square roots (unless it simplifies to whole numbers)
Let’s go one by one:
6.
–7x + y → Both terms have variables with exponent 1 (which is fine).
✔ POLYNOMIAL
7.
4x / y → Variable y is in denominator →
✘ NOT POLYNOMIAL
8.
8mn⁻¹ → Negative exponent on n →
✘ NOT POLYNOMIAL
9.
5(x – 3) → Expand: 5x – 15 → all exponents are 1 or 0 →
✔ POLYNOMIAL
10.
√(6m²) + 1 → √(6m²) = m√6 → which is same as (√6)m¹ → still a valid term? Wait — actually, √(6m²) simplifies to |m|√6, but since we’re dealing with polynomials over real numbers and assuming m ≥ 0 for simplicity, it becomes a linear term. BUT — strictly speaking, if the original expression has a radical that doesn’t simplify to a rational coefficient times a power, it may not be considered a polynomial. However, √(6m²) = √6 * |m| — absolute value makes it NOT a polynomial unless restricted. But in many school contexts, if it simplifies to a monomial,
