Final answer:
The expression (2 + y)(By? - 2y3) = y(By? - 2y3) + y(3y2 - 2y3) is an example of the distributive property in algebra.
Step-by-step explanation:
The expression (2 + y)(By? - 2y3) = y(By? - 2y3) + y(3y2 - 2y3) is an example of the distributive property in algebra.
The distributive property states that when you multiply a number (or in this case, a variable expression) by a sum or difference, you can distribute the multiplication to each term inside the parentheses.
In this example, we distribute the multiplication of (2 + y) to each term inside the parentheses, resulting in the expression on the right-hand side of the equation.
