Solve This and I will surely mark u as brainlist
But answer it correct​

Answer 1

we will not cancel anything coz power is different

Answer 2

Answer:

$({a}^{2} + 1) {b}^{2} - {b}^{2} - {a}^{2} \\ {a}^{2} {b}^{2} + {b}^{2} - {b}^{4} - {a}^{2} \\ {a}^{2} {b}^{2} - {a}^{2} + {b}^{2} - {b}^{4} \\ {a}^{2} ( {b}^{2} - 1) - {b}^{2} ( {b}^{2} - 1) \\ ( {b}^{2} - 1)( {a}^{2} - {b}^{2} )$
