Question

solution of (a+b)^3 + (a-b) ^3

Answer 1

Step-by-step explanation:

Here, [(a+b)^3= a^3+b^3+3ab(a+b)]---------1equation

And next is

[(a-b)^3= a^3-b^3-3ab(a-b)]-2equation

According to question:

a^3+b^3+3a^2×b+3ab^2-[a^3-b^3-3a^2×b+3ab^2]

a^3+b^3+3a^2×b+3ab^2-a^3+b^3+3a^2×b-3ab^2

= 2b^3+6a^2b answer
