## How can we describe 3x 2 as an expression?

Answer: In each of the terms 3x 2 and 7x, x is a variable, and in both terms, we are multiplying a number by the variable. In the first term, 3x 2, 3 is being multiplied by the variable, so 3 is a coefficient. In the second term, 7x, 7 is being multiplied by the variable, so 7 is a coefficient.

## What is a basic expression?

Expressions are basically the building blocks of Statements, in that every BASIC statement is made up of keywords (like GOTO, TO, STEP) and expressions. So expressions include not just the standard arithmetic and boolean expressions (like 1 + 2), but also lvalues (scalar variables or arrays), functions, and constants.

## What are the parts of an expression?

A mathematical expression is an expression that contains numbers, variables, symbols, and operators connected with addition, subtraction, multiplication, and division. Each mathematical expression has different parts. Three of these parts are terms, factors, and coefficients.

## What are the factors in an expression?

A factor in an expression is something that is multiplied by something else. It can be a number, variable, term or any other longer expression. For example, the factors of 2xy are 2, x and y.

## What are the terms in an expression?

A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.

## How do you simplify expressions?

To simplify any algebraic expression, the following are the basic rules and steps:
1. Remove any grouping symbol such as brackets and parentheses by multiplying factors.
2. Use the exponent rule to remove grouping if the terms are containing exponents.
3. Combine the like terms by addition or subtraction.
4. Combine the constants.

## What is equation and expression?

Equation. An expression is a number, a variable, or a combination of numbers and variables and operation symbols. An equation is made up of two expressions connected by an equal sign. Word example: The sum of 8 and 3.

## How do you factor an expression with 2 terms?

How to Factor Trinomials with Two Variables?
1. Multiply the leading coefficient by the last number.
2. Find the sum of two numbers that add to the middle number.
3. Split the middle term and group in twos by removing the GCF from each group.
4. Now, write in factored form.

## What are the 4 types of factoring?

The four main types of factoring are the Greatest common factor (GCF), the Grouping method, the difference in two squares, and the sum or difference in cubes.
