Combining Like Terms and Constants

The video tutorial explains how to combine like terms in algebraic expressions. It begins by introducing the concept and discussing the unknown values of variables. The instructor provides examples of combining like terms, simplifying expressions, and verifying the results. The tutorial concludes with a summary of key takeaways, emphasizing the importance of understanding variable values and the process of combining terms.

What is the first step in combining like terms?

• Determine the variable values

• Identify the coefficients

• Recognize the like terms

• Add all numbers together

Why is it important to understand the value of X when combining like terms?

• To calculate the exact result

• To ensure the terms are like terms

• To determine the sign of the result

• To avoid errors in addition

If you have 1X and 5X, what is the result when combined?

• 7X

• 4X

• 6X

• 5X

What happens when you combine 6X and -2X?

• 0X

• 2X

• 4X

• 8X

How do you combine the constants 3 and -4?

• Divide to get 0.75

• Add them to get 7

• Subtract to get -1

• Multiply to get 12

What is the result of combining 6X, -2X, 3, and -4?

• 6X + 1

• 6X - 1

• 4X - 1

• 4X + 1

Why does X + X equal 2X?

• Because you add the coefficients

• Because X is a variable

• Because X is always 1

• Because X is a constant

If X equals 1, what is X + X?

• 3

• 4

• 1

• 2

What is the result of 2 * 1 when X equals 1?

• 1

• 2

• 4

• 3

What does the example of X = 1 demonstrate?

• That X cannot be negative

• That combining like terms is flexible

• That X is always 1

• That X is a constant
