Write the following
enpanded form(2x-2)cube​

Answer 1

Step-by-step explanation:

(a-b)3 =a3-b3-3a2b+3ab2

(2x-2)3=8x3-8-24x2+24x

=8(x3-1)-24x(x+1)

hope this helps you!!!

Answer 2

Answer:

8x³-24x²+24x-8

Step-by-step explanation:

in this case, we will use the identity

(a-b)³=a³-b³-3ab(a-b)

hence,

(2x-2)³

=(2x)³-(2)³-3(2x)(2)(2x-2)

=8x³-8-12x(2x-2)

=8x³-8-24x²+24x

=8x³-24x²+24x-8
