Question

Expand (2p+q)^3

Please help

Answer 1

Answer:

8p³+q²+12p²q+6pq²

(a+b) ³ = a³ + b³+ 3a²b + 3ab²

Answer 2

Answer:

8p^3 + q^3 + 6pq(2p+q)

Step-by-step explanation:

since,expansion for (a+b)^3 = a^3 + b^3 + 3ab(a+b)

applying it on (2p+q)^3 we get:

(2p)^3 + q^3 + 3×2p×q(2p+q)

= 8p^3 + q^3 + 6pq(2p+q)
