Question

expand (2p - 1/2p) cube​

Answer 1

Answer:

(51/8)p3-3p

Or (27/8)p3

Step-by-step explanation:

For Answer 1

(2p-1/2p)(2p-1/2p)(2p-1/2p)

=(4p2-2*2*1/2+1/4p2)(2p-1/2p)

=(4p2-2+1/4p2)(2p-1/2p)

=8p3-4p+1/2p3-2p3+1p-1/8p3

=6p3+(3/8)p3-3p

=((48+3)/8)p3-3p

=(51/8)p3-3p

For answer 2

(2p-(1/2)p)^3

=(((4-1)/2)p)^3

=((3/2)p)^3

=(27/8)p^3
