Algebraic expression example

Jul 19, 2022 · Based on the number of terms, we can classify algebraic expressions into three types, monomial, binomial, and trinomial. Monomial: An algebraic expression having only one term is called a monomial. Examples of monomials are \ (5,2 x, 3 a^ {2}, 4 x y\), etc. An algebraic expression having two or more variables called polynomial in those variables. Powers are here non negative integer. Example 1. 8a 2 b 3 − 5a 2 b + 7ab − 1 ⁄ 5 is a polynomial in two variables a and b. degree of its terms are 2+3, 2+1, 1+1, 0.

Numbers or Constants; Examples: 1, 6, 8, 27, 32, etc. Variables or Letters; Examples: x, y, a, h, p, etc. Arithmetic Operations; Examples: + (addition), - (subtraction) , \times (multiplication) , ÷ (division) An algebraic expression is a set of terms with letters and numbers that are combined using addition (+), subtraction (-), multiplication ( ) and division (÷). An expression that contains two terms is called a binomial. E.g.2x +3y or 2 −5y2 etc. E. g. 2 x + 3 y o r 2 − 5 y 2 e t c. An expression that contains three terms is called a trinomial.Simplify each expression to lowest terms. 1. 2a - 4b +3ab -5a +2b 2. 4 (2x+1) - 3x 3. 4 (p - 5) +3 (p +1) 4. 6 (p +3q) - (7 +4q) 5. 4rs -2s - 3 (rs +1) - 2s Answer Key 1. -3a - 2b + 3ab 2. 5x + 4 3. 7p - 17 4. 6p + 14q - 7 5. rs - 4s - 3 So... how did you do? Are you ready to move onto the next unit, Solving Equations? You're doing a great job! The following diagram is an example of an algebraic expression: In the expression 4 x + 3, x is the variable. A variable is a letter that represents an unknown value. Other examples of variables are a, b, y, t. 4 is the coefficient of x. The coefficient is a numerical value used in conjunction with a variable. 3 is the constant. cat 980m specs xa
