Question

Simplify (a^2-b^2)(a^2+b^2)-(a^2-b^2)^2​

Answer 1

Answer:

there are 2 ways to solve

Answer 2

Answer:

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

Step-by-step explanation:

$( {x}^{2} - {y}^{2} )( {x}^{2} + {y}^{2} ) - ( {x}^{2} - {y}^{2} )^{2}$

Taking x^2 -y^2 common , we get :-

$( {x}^{2} - {y}^{2} )( {x}^{2} + {y}^{2} - {x}^{2} + {y}^{2} )$

$( {x}^{2} - {y}^{2} )(2 {y}^{2} )$
