Answer:
(1 - 4x)(1-4x)(1-4x)
Step-by-step explanation:
1 - 64x³ - 12x + 48x²
= 1 - 12x + 48x² - 64x³
= 1³ - 3×1²×4x + 3×1×(4x)² - (4x)³
= ( 1 - 4x )³
************************************
We know the algebraic identity:
( a-b)³ = a³ - 3a²b + 3ab³ - b³
*************************************
=( 1 - 4x)(1-4x)(1-4x)
