Factorize
1,458x^3 - 2
2(729)x ^3-2 = 2 (729x ^3 -1)
Then use the next factoize form :
(ax ^3 - y^3) = (ax-y) (ax^2+axy + y^2)
where (a^3x ^3 - y^3) = (729x ^3 -1)
a^3 =729
a= 9
Using the form
(729x ^3 -1) = (9x-1) (9^2x^2+9x+1)
9^2 = 81
(9x-1) (9^2 x^2+9x+1) = (9x-1) (81 x^2+9x+1)
The whole exprresion is 2(9x-1) (81 x^2+9x+1)
The answer is the option A
