Answer 2

b⁴ - x⁴ = ( b + x ) ( b - x ) ( b² + x² )

Given :

The expression b⁴ - x⁴

To find :

Factorise the expression

Formula :

a² - b² = ( a + b ) ( a - b )

Solution :

Step 1 of 2 :

Write down the given expression

The given expression is b⁴ - x⁴

Step 2 of 2 :

Factorise the expression

$\sf {b}^{4} - {x}^{4}$

$\sf = {( {b}^{2} )}^{2} - {( {x}^{2} )}^{2}$

$\sf = ( {b}^{2} + {x}^{2} )( {b}^{2} - {x}^{2} )$

$\sf = ( {b}^{2} + {x}^{2} )(b + x)(b - x)$

$\sf =(b + x)(b - x) ( {b}^{2} + {x}^{2} )$
