## Is 2x and expression?

A term is defined as a number, variable, or some combination of numbers and/or variables being multiplied together. Even though 2x has two parts (2 and x), since they are being multiplied together, 2x is considered a single term (a monomial expression).

**Which value of x makes the expression undefined?**

A rational expression is undefined when the denominator is equal to zero. To find the values that make a rational expression undefined, set the denominator equal to zero and solve the resulting equation. Example: 0 7 2 3 x x − Is undefined because the zero is in the denominator.

**What is the value X?**

more The letter “x” is often used in algebra to mean a value that is not yet known. It is called a “variable” or sometimes an “unknown”. In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn’t have to be “x”, it could be “y”, “w” or any letter, name or symbol.

### What is the expression of 2x?

The verbal expression for 2x is: “Two times some value.” or “The product of two and some value.”

**What is an equivalent expression calculator?**

**What value for x makes the denominator equal to zero?**

Example | ||
---|---|---|

Problem | Identify the domain of the expression. | |

Find any values for x that would make the denominator equal to 0 by setting the denominator equal to 0 and solving the equation. | ||

x = 0 | The values for x that make the denominator equal 0 are excluded from the domain. | |

Answer | The domain is all real numbers except 0. |

#### How do you know if an expression is undefined?

How do we know when a numerical expression is undefined? It is when the denominator equals zero. When we have a denominator that equals zero, we end up with division by zero. We can’t divide by zero in math, so we end up with an expression that we can’t solve.

**What is the value of expression?**

The value of a mathematical expression is the result of the computation described by this expression when the variables and constants in it are assigned values. The value of a function, given the value(s) assigned to its argument(s), is the quantity assumed by the function for these argument values.

**What is example of value in math?**

Mathematics: a number, or the result of a calculation. Example: 3 × 4 gives the value of 12. Money: how much something is worth. Example: the value of this coin is one dollar.
