The equation (x³+2x²) (3x²+2x+1)=x³ (3x² + 2x+1) + 2x² (3x² + 2x+1) is an example of the Distributive Property. The Distributive Property states that when multiplying two terms, you can multiply each term in one expression by each term in the other expression. In this equation, the terms in the first expression (x³+2x²) are multiplied by each term in the second expression (3x²+2x+1). This is why the equation is an example of the Distributive Property.
