Answer 1

Step-by-step explanation:

$( {x}^{2} - ay)( {x}^{2} - ay)$

$= {x}^{4} - a {x}^{2} y - a {x}^{2} y + {a}^{2} {y}^{2}$

$= {x}^{4} - 2a {x}^{2} y + {a}^{2} {y}^{2}$

Answer 2

Step-by-step explanation:

$( {x}^{2} - ay)( {x}^{2} - ay)$

$= {x}^{4} - a {x}^{2} y - a {x}^{2} y + {a}^{2} {y}^{2}$
