Question

factories a⁴ - 16b⁴ ​

Answer 1

Answer:

a^4 - 16 b^4

( a ² ) ² - ( 4b²) ²

( a² + 4b ² ) ( a² - 4b ² )

( a² - 4b ² ) [ ( a² )- ( 2b ) ² ]

( a² + 4b²) ( a + 2b ) ( a - 2b )

Answer 2

Answer:

a⁴ - b⁴ = (a²)² - (b²)² = (a² + b²)(a² - b²) = (a² + b²)(a + b)(a - b); three factors.

a⁴ - b⁴ = {(a²+b²)(a+b)}(a-b) = {a³ + ab(a+b)+ b³}(a-b); two factors.

a⁴ - b⁴ = {(a²+b²)(a-b)}(a+b) = {a³-ab(a-b)-b³}(a+b); two factors.
