Question

(a+b)^3+ (a-b)^3 factorise the question.... step by step... ​

Answer 1

Answer:

2a(a^2+3b^2)

Step-by-step explanation:

We will write the equation by putting the formulas of both, then we will get

a^3+b^3+3ab(a+b) + a^3-b^3-3ab(a-b)

Then, we will open the brackets

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

Now, after cancelling b^3 and 3a^2b

We get,

2a^3+6ab^2

We get the answer i.e. 2a(a^2+3b^2)
