Expanding Binomial Expressions to the Power of 1

When expanding binomial expressions to the power of 1, the result is simply the original expression itself. Let's calculate the expansions for the given expressions.

1. (3y-4)²: - The expansion of (3y-4)² is calculated by squaring each term and then adding the product of the two terms multiplied by 2. - The expansion is: (3y-4)² = 9y² - 24y + 16.

2. (2x+b)²: - Similarly, the expansion of (2x+b)² is calculated by squaring each term and then adding the product of the two terms multiplied by 2. - The expansion is: (2x+b)² = 4x² + 4bx + b².

So, the expanded forms of the given expressions are: 1. (3y-4)² = 9y² - 24y + 16 2. (2x+b)² = 4x² + 4bx + b²
