Answer:
mark me as brainliest
Step-by-step explanation:
as we can see that 3 is on brackets means the numbers or variables inside will also have the power 3
2³- c³ + 2³+ c³
now we don't know what exactly c is so we will consider as 1
now equation will be
8-1+8+1

Let (2-c)=a
and (2+c)=b
Then
a^3-b^3= (a-b) (a^2+ab+b^2)
(a-b)= 2-c-2-c=2c
ab=4-c^2
(a+b)= 4
=>(a+b)^2= 16
=>(a^2+ab+b^2)= 16-4+c^2
=>(a-b) (a^2+ab+b^2)= (12+c^2) 2c= 24c+c^3
