The expression -2 3x can be represented as "negative two times three times a variable x" or "negative two multiplied by three times x." The expression 3x - 2 can be phrased as "three times a variable x minus two." Both expressions involve multiplication and subtraction of the variable x with constants.

What does the word expression mean in a math question?
In mathematics, an expression refers to a combination of numbers, variables, and mathematical operations (such as addition, subtraction, multiplication, and division) that represent a value. It does not include an equality sign, distinguishing it from equations. For example, (3x + 5) is an expression, while (3x + 5 = 10) is an equation. Expressions can be simplified or evaluated, but they do not assert a relationship between two quantities.
What is a group of variables and numbers separated by operators is called?
A group of variables and numbers separated by operators is called an expression. In mathematics, expressions can involve operations such as addition, subtraction, multiplication, and division, and they represent a value or relationship without an equality sign. Examples include algebraic expressions like (3x + 5) or numerical expressions like (2 + 4 \times 3).
Is 2(6-3x) plus x equivalent to 2(3x) plus x?
To determine if (2(6-3x) + x) is equivalent to (2(3x) + x), we can simplify both expressions. Starting with the left side: (2(6-3x) + x = 12 - 6x + x = 12 - 5x). Now for the right side: (2(3x) + x = 6x + x = 7x). Since (12 - 5x) is not equal to (7x), the two expressions are not equivalent.
What a number being multiplied by a variable?
When a number is multiplied by a variable, it creates a term that represents the product of the two. For example, in the expression (3x), the number 3 is multiplied by the variable (x). This means that the value of (3x) will change depending on the value of (x). Such expressions are commonly used in algebra to represent relationships and solve equations.
How can expressions be written?
Expressions can be written using mathematical symbols, variables, and constants to represent relationships or operations. They often include operators such as addition (+), subtraction (−), multiplication (×), and division (÷), along with parentheses to indicate the order of operations. For example, an expression like (3x + 5) combines a variable (x) with constants and coefficients. Additionally, expressions can also be verbalized in natural language to describe their meaning or purpose.

Simplifying rational expressions 6x-5y plus -3x-4y?
(6x - 5y) + (-3x - 4y) =6x - 5y - 3x - 4y =3x - 9y =3 (x - 3y)
What are the factors of 3x-2y and 3x 2y?
Well, isn't that just a happy little math question! Let's take a look at these expressions together. The factors of 3x - 2y are (3x - 2y) and 1, while the factors of 3x + 2y are (3x + 2y) and 1. Remember, in math, factors are numbers or expressions that can be multiplied together to get a specific result. Just like painting, math can be a beautiful and creative process!
