Answer 2

To simplify the expression (1,3²p + 2,5q²)²(a²-5)(a²+5)(4m²+6n)(6n-4m²), you can start by breaking it down into smaller parts and then simplify each part separately. Let's break it down step by step:

1. Simplify the first term: (1,3²p + 2,5q²)²

(1,3²p + 2,5q²)² = (1.69p + 6.25q²)² (Squaring each term)

Now, square each term within the parentheses:

(1.69p)² + 2 * (1.69p) * (6.25q²) + (6.25q²)²

2. Simplify the second term: (a²-5)(a²+5)

This is the difference of squares, so you can use the formula: (a² - b²) = (a + b)(a - b)

(a + 5)(a - 5)

3. Simplify the third term: (4m²+6n)(6n-4m²)

This is also the difference of squares, so you can use the formula: (a² - b²) = (a + b)(a - b)

(4m² + 6n)(-4m² + 6n)

Now, let's combine all the simplified terms:

(1.69p)² + 2 * (1.69p) * (6.25q²) + (6.25q²)² * (a + 5)(a - 5) * (4m² + 6n)(-4m² + 6n)

Now, you can expand and simplify further if needed, but this is the basic form of the expression after breaking it down and simplifying each part.
