Answer 2

It looks like you've provided two algebraic expressions, and I assume you're looking for help in simplifying them. Let's simplify each expression step by step:

1. (3a+5)(3a-5) Using the difference of squares formula (a² - b² = (a+b)(a-b)), we can simplify this expression: (3a+5)(3a-5) = (3a)² - (5)² = 9a² - 25

2. (x-4)(x²+2x-3) To simplify this expression, we'll use the distributive property (FOIL method): (x-4)(x²+2x-3) = x³ + 2x² - 3x - 4x² - 8x + 12 Combine like terms: x³ - 2x² - 11x + 12

So, the simplified expressions are:

1. 9a² - 25
2. x³ - 2x² - 11x + 12
