Tolong jabarkan ya gaes . tlng cepat jwb .. Bsk di kumpulkan 1. (4p - 3) (5 - q) 2. (3M + 5) (3M + 5) 3. (4n + 9) (4n + 5)

1. (4p-3)(5-p)
= 20p - 4p^2 - 15 +3p
= -4p^2 + 20p + 3p - 15
= -4p^2 + 23p -  15
= 4p^2 - 23p + 15

2. (3m+5)(3m+5)
= 9m^2 + 15m + 15m + 25
= 9m^2 + 30m + 25

3. (4n+9)(4n+5)
= 16n^2 + 20n + 36n + 45
= 16n^2 + 56n + 45
