Answer 2

1. (2x^2 - 1)(2x^2 + 1) can be simplified using the difference of squares formula: (2x^2 - 1)(2x^2 + 1) = (2x^2)^2 - (1)^2 = 4x^4 - 1

2. (1 + 3ab)(1 - 3ab) can also be simplified using the difference of squares formula: (1 + 3ab)(1 - 3ab) = (1)^2 - (3ab)^2 = 1 - 9a^2b^2

3. (8ab + 5)(5 - 8ab) can be simplified by applying the distributive property: (8ab + 5)(5 - 8ab) = 40ab - 64a^2b^2 + 25 - 40ab = 25 - 64a^2b^2

4. (10cx - 6)(10cx + 6) can be simplified using the difference of squares formula: (10cx - 6)(10cx + 6) = (10cx)^2 - (6)^2 = 100c^2x^2 - 36

5. (8 + 9cd)(9cd - 8) can be simplified using the difference of squares formula: (8 + 9cd)(9cd - 8) = (8)^2 - (9cd)^2 = 64 - 81c^2d^2

6. (0.2t - 0.5u)(0.2t + 0.5u) can be simplified using the difference of squares formula: (0.2t - 0.5u)(0.2t + 0.5u) = (0.2t)^2 - (0.5u)^2 = 0.04t^2 - 0.25u^2

These are the simplified forms of the given expressions.
