Answer 2

Answer:

$\huge{\boxed{\sf{(a^{2}-b^{2}-ab )(a^{2}-b^{2}+ab )}}}$

Step-by-step explanation:

$\huge{\boxed{\sf{SOLUTION-}}}$

${ {a}}^{4} + 4 {b}^{4} - 5 {a}^{2} {b}^{2} \\ ( { {a}^{2} })^{2} + ({2 {b}^{2} })^{2} - 4 {a}^{2} {b}^{2} - {a}^{2} {b}^{2} \\ ({ {a}^{2} })^{2} + ({2b}^{2})^{2} - 4 {a^{2} b}^{2} - ({ab})^{2} \\ ( {a}^{2} - {b}^{2} )^{2} - (ab)^{2} \\ ( {a}^{2} - {b}^{2} - ab)( {a}^{2} - {b}^{2} + ab) \\ ((a + b)(a - b) - ab)((a + b)(a - b) + ab)$

$\huge{\boxed{\sf{(a^{2}-b^{2}-ab )(a^{2}-b^{2}+ab )}}}$
