Explanation:

1.
(x + 6)(x + 4)
= x^2 + 4x + 6x + 24
= x^2 + 10x + 24

2.
(y - 9)(y+2)
= y^2 + 2y - 9y - 18
= y^2 - 7y - 18

3.
(m + 7)(m - 5)
= m^2 - 5m + 7m - 35
= m^2 + 2m - 35

4.
(2x + 3)(4x + 1)
= 8x^2 + 2x + 12x + 3
= 8x^2 + 14x + 3

5.
(4y - 5)(y + 4)
= 4y^2 + 16y - 5y - 20
= 4y^2 + 11y - 20
