Final answer:
The technique that simplifies algebraic expressions is combining like terms and using the distributive property.
Step-by-step explanation:
The technique that simplifies algebraic expressions is combining like terms.
To simplify an algebraic expression, you can combine terms that have the same variables and exponents. You add or subtract the coefficients of these terms to obtain a simplified expression. For example, if you have the expression 2x + 3x + 5x, you can combine the x terms to get 10x.
Another technique to simplify expressions is to use distributive property. This involves multiplying a number or term outside parentheses with each term inside the parentheses. For example, if you have the expression 2(x + 3), you would distribute the 2 to both x and 3 to get 2x + 6.
