Question

Simplify (2-c)³+(2+c)³​

Answer 1

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

answer 16

Answer 2

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
