Question

Solve:

27p3 - 1/216 - 9/2p2 1/4p

Answer 1

HEY!!

27p3 - 1/216 - 9/2p2 + 1/4p

(3p)3 - 1/ (6)3 - 3 (3p)2 (1/6) + 3 (3p) (1/6)2


On camparing the above expansion with the identity (a+b)3 = a3 + b3 + 3a2b+ 3ab2 we get,

(3p - 1/6)3

Answer 2

hy
here is your answer
=================
*************************

➡27p³- 1/216 - 9/2p2 + 1/4p

➡(3p)³ - 1/ (6)³ - 3 (3p)²(1/6) + 3 (3p) (1/6)²

➡On camparing the above expansion with the identity

➡(a+b)³= a³+ b³+ 3a²b+ 3ab²

➡ we get,

➡(3p - 1/6)³
