Collecting Like Terms in Algebra: Simplifying Expressions

The video tutorial explains the concept of like terms in algebra, emphasizing their role in simplifying expressions. It defines terms and demonstrates how to collect like terms using coefficients. The tutorial provides examples of both like and unlike terms, illustrating why unlike terms cannot be combined. It also covers subtraction of like terms and discusses terms with different powers. The video concludes with complex examples involving multiple types of terms, reinforcing the importance of identifying and combining like terms to simplify algebraic expressions.

Why is it beneficial to collect like terms in algebraic expressions?

• To make expressions harder to solve

• To simplify and shorten expressions for easier use

• To make expressions longer and more complex

• To increase the number of terms in an expression

What is a term in an algebraic expression?

• A distinct part of an expression associated with a sign

• A number without a variable

• A variable without a coefficient

• A complete equation

How do you identify like terms in an expression?

• By counting the number of terms

• By identifying terms with the same coefficient

• By finding terms with different variables

• By looking for terms with the same variable and power

What is the result of adding 4X and 2X?

• 6X

• 2X

• 8X

• 4X

Why can't you combine 5X and 3Y?

• They have the same coefficient

• They are unlike terms with different variables

• They are like terms

• They are both constants

What happens when you subtract 3X from 5X?

• You get 0

• You get 3X

• You get 8X

• You get 2X

In the expression 2X^2 + X, why can't the terms be combined?

• They are unlike terms with different powers

• They have different coefficients

• They are both constants

• They are already simplified
