Question

x^6/343+343/x^6 factorise it

Hello is anybody there? ​

Answer 1

Answer:

$x^6/343 + 343/x^6$

$( x^2 )^3/7^3 + 7^3/( x^2 )^3$

$( x^2/7 )^3 + ( 7/x^2)^3$

     Using formula, $x^3+ y^3 = ( x + y ) (x^2 - xy + y^2 )$

$(x^2/7 + 7/x^2)[(x^2/7)^2-(x^2/7)(7/x^2)+(7/x^2)^2]$

$(x^2/7+7/x^2)(x^4/49- 1 + 49/x^4)$
