Answer 2

Step-by-step explanation:

${a}^{4} - 2 {a}^{2} {b}^{2} + {b}^{4} \\ = {a}^{4} - ( {a}^{2} {b}^{2} + {a}^{2} {b}^{2} ) + {b}^{4} \\ = {a}^{4} - {a}^{2} {b}^{2} - {a}^{2} {b}^{2} + {b}^{4} \\ = {a}^{2} ( {a}^{2} - {b}^{2} ) - {b}^{2} ( {a}^{2} - {b}^{2} ) \\ = ( {a}^{2} - {b}^{2} ) ( {a}^{2} - {b}^{2} ) \\ = {( {a}^{2} - {b}^{2} ) }^{2} \\ or \\ = (a + b)(a - b)(a + b)(a - b)$
