Parts of an algebraic expression Middle school math Pinterest
An algebraic expression (or) a variable expression is a combination of terms by the operations such as addition, subtraction, multiplication, division, etc. For example, let us have a look at the expression 5x + 7. Thus, we can say that 5x + 7 is an example of an algebraic expression. Here are more examples: 5x + 4y + 10 2x 2 y - 3xy 2

While a variable represents an unknown quantity and may change, the constant term does not change. Example 1.4.1 1.4. 1: List all coefficients and variable parts of each term: 10a2 − 5ab −b2 10 a 2 − 5 a b − b 2. Solution. We want to think of the third term in this example −b2 − b 2 as −1b2 − 1 b 2. Terms.

a + b = b + a a × b = b × a The associative law tells us that in addition or multiplication, we can associate the terms or factors as we please. For variables a , b , and c : ( a + b) + c = a + ( b + c) ( a × b) × c = a × ( b × c)

An algebraic expression can have two types of terms, like and unlike terms. Now let's take a look at a few examples of algebraic expressions: x + 4 is an algebraic expression with two terms, x and 4, one variable, x, and a constant, 4. y\(^3\) + 2y\(^2\) + y - 9 is an algebraic expression with four terms, one variable, y and a constant, -9.

To write algebraic expressions and equations, assign a variable to represent the unknown number. In the table below, the letter "x" is used to represent the unknown. In translation problems, the words sum, total, difference, product and quotient imply at least two parts - use parentheses when a sum or difference is multiplied.

Here is a table that summarizes common words for each operation: For example, the word "product" tells us to use multiplication. So, the phrase "the product of 8 and k " can be written as 8 k . Let's take a look at a trickier example Write an expression for " m decreased by 7 ". Notice that the phrase "decreased by" tells us to use subtraction.

Let us consider the collection of all algebraic expressions that do not contain variables in the denominators of fractions and where all exponents on the variable quantities are whole numbers. Expressions in this collection are called polynomials. Some expressions that are polynomials are Example 4.4.1
