Question

To verify the experimentally the identity (a+b)^3=a^3+b^3+3ab(a+b)​

Answer 1

(a+b)3=(a+b)*(a+b)*(a+b)

=(a2+ab+ab+b2)*(a+b)

=a3+a2b+a2b+ab2+a2b+ab2+ab2+b3

a3+3a2b+3ab2+b3

Answer 2

Step-by-step explanation:

for verifying

(a+b)^3

we may use like this

(a+b)(a+b)(a+b)

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

a^2+2ab+b^2(a+b)

a{a^2+2ab+b^2}+b{a^2+2ab+b^2}

a^3+2a^2b+ab^2+ba^2+2ab^2+ b^3

a^3+3a^2v+3ab^2+b^3

a^3+b^3+3ab(a+b}
