Question

factorise:a^12 + b^12

Answer 1

heya man !! good question !!


a^12 - b^12 

USE FORMULA a^2 - b^2 = ( a+b) ( a-b) 

(a^6 + b^6) ( a^6 - b^6) 

( a^6 + b^6) ( a^3 + b^3) ( a^3 - b^3) 

USE FORMULAS a^3 + b^3 = ( a+b) ( a^2 -ab + b^2) 

AND a^3 - b^3 = ( a-b) ( a^2 + ab + b^2) 

(a^2 + b^2) ( a^4 -a^2b^2 + b^4) ( a+ b) (a^2 -ab+b^2) ( a-b) (a^2 +ab + b^2) 

hope it helps

Answer 2

Answer:

a^12 - b^12

= (a^6)^2 - (b^6)^2

= (a^6 + b^6)(a^6 - b^6)

= (a^2 + b^2)(a^4 - a^2b^2 + b^4)(a - b)(a + b)(a^2 - ab + b^2)(a^2 + ab + b^2)

= (a - b)(a + b)(a^2 + b^2) (a^2 - ab + b^2)(a^2 + ab + b^2)(a^4 - a^2b^2 + b^4)
