Adding Linear Expressions

The video tutorial introduces linear expressions, explaining that they are algebraic expressions without exponents. It demonstrates how to add linear expressions using both vertical and horizontal methods, emphasizing the importance of identifying like terms. The tutorial provides examples for practice and encourages viewers to try both methods to determine which works best for them. The video concludes with a summary of the results obtained using both methods.

What is a key characteristic of a linear expression?

• It is always a constant.

• It includes quadratic terms.

• It has variables without exponents.

• It contains variables with exponents.

Which method does the instructor prefer for adding linear expressions?

• Horizontal method

• Vertical method

• Diagonal method

• Graphical method

When using the vertical method, what is important to remember?

• Align the terms randomly.

• Align the like terms vertically.

• Start adding from the left.

• Use only constants.

What is the result of adding the expression n + 8 and n - 12 using any method?

• n + 20

• 2n - 4

• 2n + 4

• n - 4

What is the simplified result of adding 2W - 9 and -4W - 5?

• -2W - 14

• 2W + 14

• 6W - 14

• -6W + 4
