Question

a4-b4 divide by a-b how

Answer 1

$= > \frac{ {a}^{4} - {b}^{4} }{a - b} \\ \\ \\ \\ = > \frac{ {( {a}^{2} )}^{2} - {(b {}^{2}) }^{2} }{a - b}$



We know ,
x² - y² = ( x + y ) ( x - y )


$= > \frac{( {a}^{2} - {b}^{2} )( {a}^{2} + {b}^{2}) }{a - b} \\ \\ \\ \\ = > \frac{(a - b)( a + b)( {a}^{2} + {b}^{2} )}{a - b} \\ \\ \\ \\ = > (a + b)( {a}^{2} + {b}^{2} )$
