Step-by-step explanation:
Factorisation Identities
1. a⁴ - b⁴
= (a²)² - (b²)²
= (a² + b²)(a² - b²)
= (a² + b²)(a + b)(a - b). three factors.
2. a⁴ - b⁴
= {(a²+b²)(a+b)}(a-b)
= {a³ + ab(a+b)+ b³}(a-b) ; two factors.
3. a⁴ - b⁴
= {(a²+b²)(a-b)}(a+b)
= {a³-ab(a-b)-b³}(a+b); two factors.
Hope this helps.
