Expanding Linear Expressions with Rational Coefficients

This video tutorial teaches how to expand linear expressions with rational coefficients using the properties of real numbers. It covers key vocabulary, such as linear expressions and rational coefficients, and explains the commutative, associative, and distributive properties. The tutorial highlights common mistakes in distribution and demonstrates the distributive property using an area model. An advanced example is provided to show the application of these concepts in more complex scenarios.

Summarize the process of expanding the expression 3 times the quantity 2x plus 4.
