An expression which contains two unlike terms is called _______.a)bino...
Explanation:
- When we talk about expressions, we are referring to mathematical expressions that consist of numbers, variables, and operations such as addition, subtraction, multiplication, and division.
- An expression that contains two unlike terms is called a binomial.
- Let's break down the different types of expressions to understand this concept better:
1. Monomial: A monomial is an expression that consists of only one term. It can be a constant, a variable, or a product of a constant and one or more variables. For example:
- 5x
- 3y^2
- 2xy^3
2. Binomial: A binomial is an expression that consists of two unlike terms connected by an operation. The operation can be addition or subtraction. For example:
- 2x + 3y
- 4a - 5b^2
- x^2 - 2xy
3. Trinomial: A trinomial is an expression that consists of three unlike terms connected by operations. The operations can be addition or subtraction. For example:
- x^2 + 2xy - y^2
- 3a^2 - 4ab + 5b^2
- 2x^3 - 3x^2 + 4x
- In the given options, the correct answer is option 'A' - binomial - because it represents an expression with two unlike terms.
- Option 'B' - monomial - is incorrect because a monomial consists of only one term.
- Option 'C' - trinomial - is incorrect because a trinomial consists of three terms.
- Option 'D' - None of these - is incorrect because the expression does fall into one of the defined categories, which is a binomial.
Therefore, the correct answer is option 'A' - binomial.
