27c6-64d6
Rewrite 27c6 as (3c2)3.
(3c2)3-64d6
Rewrite 64d6 as (4d2)3.
(3c2)3-(4d2)3
Since both terms are perfect cubes, factor using the difference of cubes formula, a3-b3=(a-b)(a2+ab+b2) where a=3c2 and b=4d2.
(3c2-(4d2))((3c2)2+3c2(4d2)+(4d2)2)
Simplify.
Multiply 4 by -1.
(3c2-4d2)((3c2)2+3c2(4d2)+(4d2)2)
Apply the product rule to 3c2.
(3c2-4d2)(32(c2)2+3c2(4d2)+(4d2)2)
Raise 3 to the power of 2.
(3c2-4d2)(9(c2)2+3c2(4d2)+(4d2)2)
