simplifyy full solution ​

Answer 1

Answer:

$\frac{ { ({x}^{2}) }^{2} + { ({y}^{2}) }^{2} - 2 {x}^{2} {y}^{2} - {x}^{2} {y}^{2} }{ {x}^{2} + xy - {y}^{2} }$

$= \frac{ ({x}^{2} - {y}^{2})^{2} - {(xy)}^{2} }{ {x}^{2} + xy - {y}^{2} }$

$= \frac{( {x}^{2} - {y}^{2} + xy)( {x}^{2} - {y}^{2} - xy) }{( {x}^{2} - {y}^{2} + xy)}$

$= {x}^{2} - {y}^{2} - xy$

Hope it helps you.
