tentukan penjabaran pemangkatan a.(p-q)3

(p - q)³ = 1.p³ + 3.p²(-q) + 3(-q)²p + 1.(-q)³
            = p³ - 3p²q + 3pq² - q³

Jawab:
_______

(p-q)^3

(p−q)(p​^2−2pq+q^2 )

p(p^2−2pq+q^2​​ )−q(p​^2−2pq+q^2 )

p^3−2p^2q+pq^2−q(p^2−2pq+q^2 )

p^3−2p^2q+pq​^2−(qp^2−2q^2p+q^3)

p^3​​ −2p^2q+pq^2 −qp^2+2q^2p−q^3

​​ p^3+(−2p^2 q−p^2q)+(pq^2+2pq^2)−q^3


p^3−3p^2q+3pq^2−q^3

Keterangan:
___________
Tanda ^ => dibaca pangkat.
