Answer 1

1) (а - 2) (b + 5) = ab + 5a - 2b - 10

2) (m + n) (p - k) = mp - mk + np - nk

3) (x - 8) (x + 4) = x² + 4x - 8x - 32 = x² - 4x - 32

4) (x - 10) (x - 9) = x² - 9x - 10x + 90 = x² - 19x + 90

5) (c + 5) (c + 8) = c² + 8c + 5c + 40 = c² + 13c + 40

6) (3y + 1) (4y - 6) = 12y² - 18y + 4y - 6 = 12y² - 14y - 6
