Pertanyaan

p=7a-8b-c
q=-3a+2b-6c
hasil dari p-2q?

Answer 1

p = 7a-8b-c
q = -3a+2b-6c

p-2q
= 7a-8b-c -2(-3a+2b-6c)
= 7a-8b-c +6a-4b+12c
= 13a-12b+11c

semoga membantu :)

Answer 2

p = 7a - 8b - c
q = -3a + 2b - 6c

p - 2q = (7a - 8b - c) - 2(-3a + 2b - 6c)
p - 2q = 7a - 8b - c + 6a - 4b + 12c
p - 2q = 13a - 12b + 11c
