Welcome to understanding like terms in algebra! Today we'll learn how to identify terms that can be combined.Like terms are algebraic expressions that have exactly the same variables raised to the same powers.Let's summarize the rules for identifying like terms.Terms must have the same variables, the same exponents, but can have different coefficients.When combining like terms, we focus on the coefficients - the numbers in front of the variables.We can add these coefficients together while keeping the variable x the same.Let's add these numbers step by step. Two plus five equals seven, plus three equals ten.The result is ten x, where we keep the variable x and use our combined coefficient of ten.Now, let's look at a common mistake: trying to combine terms with different exponents.Two x and two x squared are not like terms because they have different exponents.We cannot combine these terms into four x squared. This is incorrect because the terms have different powers of x.These terms must be kept separate in our final expression.Now let's tackle expressions with multiple variables.When combining like terms with multiple variables, we add the coefficients while keeping the variables the same.With more complex expressions, first organize terms by grouping like terms together.Group all xy terms together, and all xz terms together.Then combine each group to get our final answer.Now it's your turn to practice! Try solving this problem.Let's solve this step by step. Three a b plus two a b minus five a b plus four a b.Adding the coefficients: three plus two minus five plus four equals four. So our final answer is four a b.Let's review the key points about combining like terms with multiple variables.Thanks for learning about combining like terms with Spark.E!
