Question

Escrevendo ( 2x2 y2 + 5xy − 3) ⋅ (6 − xy) na forma reduzida, obtemos?

Answer 1

$(2 {x}^{2}{y}^{2} + 5xy - 3) \times (6 - xy)$

$12 {x}^{2} {y}^{2} - 2{x}^{3} {y}^{3} + 30xy - 5 {x}^{2} {y}^{2} - 18 + 3xy$

$7 {x}^{2} {y}^{2} - 2 {x}^{3} {y}^{3} + 33xy - 18$

$- 2 {x}^{3} {y}^{3} + 7 {x}^{2} {y}^{2} + 33xy - 18$
