Question

factorise 64x^4 - 1​

Answer 1

Answer:

Factor 64x^4-1 | Mathway

Algebra Examples Rewrite 64x4 64 x 4 as (8x2)2 ( 8 x 2 ) 2 . Rewrite 1 as 12 . 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=8x2 a = 8 x 2 and b=1 .

Answer 2

Answer:

64x^4-1

(8x)²-1²

(8x+1)(8x-1)
