Question

8a^3+b^3+12a^2b+12ab^2 factories using sutaible identity​

Answer 1

Step-by-step explanation:

8a^3+b^3+12a^2b+6ab^2

(2a)^3+(b)^3+6ab (2a+b)

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

By Using, (x+y)^3=x^3+y^3+3 (x)(y)(x+y)

Putting, x = 2a, y = b

= (2a+b)^3

= (2a+b)(2a+b)(2a+b)

Answer 2

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