Factoring and the Distributive Property (Example)

The video tutorial explains how to factor the expression 3X + 4X by identifying the common factor, which is the variable X. The process involves placing X outside the parentheses and simplifying the terms inside. The tutorial also demonstrates how to verify the factored expression by distributing X back into the terms to ensure it equals the original expression. This method confirms that X times the sum of three and four is the factored form of 3X + 4X.
