15 (5x – 4)3 – 10 (5x – 4) = 5 (5x – 4) [3(5x – 4)2 – 2]
= 5 (5x – 4) [3 (25x2 – 40x + 16) – 2]
= 5 (5x – 4) (75x2 – 120x + 46)

Answer:
(30)(5x-4)(5x-4)(5x-4)
Step-by-step explanation:
let (5x-4) be y
15y³× 10y
5y(3y² × 2)
Substituting y as (5x-4)
5(5x-4) [3(5x-4)² ×2]
(5) (5x-4) (3) (5x-4)(5x-4) (2)
(30)(5x-4)(5x-4)(5x-4)
Hope it helps :)
