Answer 1

$1)2a {}^{2} (a { }^{2} - ab + b {}^{2} ) \\ 2a {}^{4} - 2a {}^{3} b + 2a {}^{2} b {}^{2} \\ 2)a(a {}^{2} - 2ab + b) - 2ab \\ a {}^{3} - 2a {}^{2} b + ab - 2ab \\ a {}^{3} - 2a {}^{2} b - ab \\ 3)x {}^{2} (a {}^{2} - 3ax + x) + 3ax {}^{2} \\ a {}^{2} x {}^{2} - 3ax {}^{3} + x {}^{3} + 3ax {}^{2} \\ a {}^{2} x {}^{2} + x {}^{3}$
