Some of the rules for simplifying expressions are listed below: The basic rule for simplifying expressions is to combine like terms together and write unlike terms as it is. Rules for Simplifying Algebraic Expressions Look at the image given below showing another simplifying expression example. By simplifying it further, we will get 3x, which will be the final answer. So, adding these two pairs of like terms will result in (6x - 3x) + (-x 2 + x 2). In this expression, 6x and -3x are like terms, and -x 2 and x 2 are like terms. Now, combining all the terms will result in 6x - x 2 - 3x + x 2. x(6 - x) can be simplified as 6x - x 2, and -x(3 - x) can be simplified as -3x + x 2. So, we will be solving the brackets first by multiplying x to the terms written inside. Here, there are two parentheses both having two unlike terms. Simplify the expression: x (6 – x) – x (3 – x). Let us take an example for a better understanding. Step 4: At last, write the expression obtained in the standard form (from highest power to the lowest power).Step 3: Add or subtract the like terms.Step 2: Use the exponent rules to simplify terms containing exponents.For example, 2x (x + y) can be simplified as 2x 2 + 2xy. Step 1: Solve parentheses by adding/subtracting like terms inside and by multiplying the terms inside the brackets with the factor written outside.To simplify algebraic expressions, follow the steps given below: We need to learn how to simplify expressions as it allows us to work more efficiently with algebraic expressions and ease out our calculations. In this article, we will be focussing more on how to simplify algebraic expressions. The general rule to simplify expressions is PEMDAS - stands for Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. Expressions refer to mathematical statements having a minimum of two terms containing either numbers, variables, or both connected through an addition/subtraction operator in between. Before learning about simplifying expressions, let us quickly go through the meaning of expressions in math.
