Answer:

The answer to your question is below

Step-by-step explanation:

1.- (x + 2)(x + 4) = x² + 4x + 2x + 8 = x² + 6x + 8

2.- (m - 5)(m + 2) = m² + 2m - 5m - 10 = m² - 3m - 10

3.- (2x + 3)(4x - 2) = 8x² - 4x + 12x - 6 = 8x² + 8x - 6

4.- (2r - 3)(r + 12) = 2r² + 24r - 3r - 36 = 2r² + 21r - 36

6.- (k - 3)(k - 1) = k² - k - 3k + 3 = k² - 4k + 3
