Question

FACTORISE x^4- 16y^4

Answer 1

Answer:

Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) a 2 - b 2 = ( a + b ) ( a - b ) where a=x2 a = x 2 and b=4y2 b = 4 y 2 . Simplify. Rewrite 4y2 4 y 2 as (2y)2 ( 2 y ) 2 .

Answer 2

Step-by-step explanation:

x^4- 16y^4

it is written as

(x^2)^2 - (4y^2)^2

by identity a^2-b^2 = (a+b) (a-b)

(x^2 + 4y^2)(x^2 - 4y^2)

(x^2 + 4y^2) (x+2y)(x-2y)
