64a³ - 1
= (4a)³ - 1³
= (4a - 1) (16a² +1+ 4a)
= (4a)³ - 1³
= (4a - 1) (16a² +1+ 4a)

64a^3 - 1
(4a) ^3 - (1) ^3 [a^3 - b^3 = ( a - b ) ( a^2 + b^2 + 2ab )
( 4a - 1 ) ( (4a)^2 + (1)^2 + 2*4a*1 ))
( 4a - 1 ) ( 16a^2 + 1 + 8a )
64a^3 - 16a^2 + 4a -1+ 32 a^2 - 8a
64a^3 - 48a^2 - 4a - 1
(4a) ^3 - (1) ^3 [a^3 - b^3 = ( a - b ) ( a^2 + b^2 + 2ab )
( 4a - 1 ) ( (4a)^2 + (1)^2 + 2*4a*1 ))
( 4a - 1 ) ( 16a^2 + 1 + 8a )
64a^3 - 16a^2 + 4a -1+ 32 a^2 - 8a
64a^3 - 48a^2 - 4a - 1
