Answer 2

hello mahi

Given as

${x}^{4} - {(x - z)}^{4} \\ ({x}^{2}) {}^{2} - ( ({x - z})^{2} )^{2} \\ \\ ({x}^{2} + ({x - z})^{2})( {x}^{2} - ({x - z})^{2} ) \\ ({x}^{2} + {x}^{2} - 2xz + {z}^{2} )( {x}^{2} - {x}^{2} + 2xz - {z}^{2} ) \\ (2 {x}^{2} - 2xz + {z}^{2} )(2xz - {z}^{2} ) \\ 4 {x}^{3} z - 4 {x}^{2} {z}^{2} + 2x {z}^{3} - 2 {x}^{2} {z}^{2} - 2x {z}^{3} - {z}^{4}$
