Question

Can someone help me step by step to the answer please? thank you!​

Answer 1

3u³ (x-1)

Rewrite x¹ as (x2)².

3u³ ((x2)-1)

Rewrite 1 as 12.

3u³ ((x²)² - 12) 2

Since both terms are perfect squares, factor using the difference of squares formula, a²b² = (a + b) (a - b) where a = b = 1. x² and

3u³ ((x² + 1) (x² − 1)).
