Question

Desenvolva o seguinte produto notável

(3 – a³)² (x + y)2

Answer 1

$\LARGE{}(3 - {a}^{3} )^{2} \times (x + y) \times 2 \\ \LARGE{}(9 - 6 {a}^{3} + {a}^{6} ) \times (x + y) \times 2 \\ \LARGE{}(9 - {6a}^{3} ) \times (2x + 2y) \\ \LARGE{}9(2x + 2y) - {6a}^{3} \times (2x + 2y) + {a}^{6} \times (2x + 2y) \\ \LARGE{}18x + 18y - 6 {a}^{3} \times (2x + 2y) + {a}^{6} \times (2x + 2y) \\ \LARGE{}18x + 18y - {12a}^{3} - \times {12a}^{3} y + {a}^{6} \times (2x + 2y) \\ \LARGE\boxed{18x + 18y - 12 {a}^{3}x - 12 {a}^{3}y + 2 {a}^{6}x + 2 {a}^{6} x + {2a}^{6} y }$
