1) xy * (x + y) = x^2y + xy^2

2) (4x + 3y) * (4x - 3y) = 16x^2 - 9y^2

3) (p³ - q²) * (p + q²) = p^4 + p^3q^2 - q^4

4) (y - k) * (y + k) = y^2 - k^2

5) (7p - 2k) * (7p + 2k) = 49p^2 - 4k^2

6) (m - n³) * (m + n³) = m^2 - n^6

7) (8y - 3p) * (3p + 8y) = 24py - 9p^2 + 64y^2

8) (x + y³) * (x - y³) = x^2 - y^6

9) (k + 5) * (k - 5) = k^2 - 25

10) (7p + 9q) * (7p - 9q) = 49p^2 - 81q^2

11) (p* - q°) * (p + q) = p^2 - q^2

12) (11x + 12y) * (11x - 12y) = 121x^2 - 144y^2

13) (2p^2 - 3q) * (2p + 3q) = 4p^3 - 9q^2

14) (0.3 - p) * (0.3 + p) = 0.09 - p^2

15) (0.1x + 6) * (0.1x - 6) = 0.01x^2 - 36

16) (1.2x - 3y) * (1.2x + 3y³) = 1.44x^2 - 9y^6
