Question

find (x2-y2)(x2+y2)​

Answer 1

Step-by-step explanation:

We know that one of the identity is

$(a−b)(a+b)= {a}^{2} - {b}^{2}$

$Here, a= {x}^{2} and b= {b}^{2} </p><p></p><p></p><p>$

Now applying the identity we get:

$</p><p>( {x}^{2} −{y}^{2})({x}^{2}+{y}^{2})=({x}^{2})^{2}−({y}^{2})^{2}=({x}^{2}×2)− \\ ({y}^{2}×2)={x}^{4}−{y}^{4}</p><p>$

$Hence, ( {x}^{2} −{y}^{2} )({x}^{2} +{y}^{2} )={x}^{2} - {y}^{2}$
