Answer 1

• Let the required number be a

The equation of the question is :-

$(2 {x}^{2} {y}^{2} - 5x + 7) + a = - 5 {x}^{2} {y}^{2} + 7x - 9$

$= > a = - 5 {x}^{2} {y}^{2} + 7x - 9 - (2 {x}^{2} {y}^{2} - 5x + 7)$

$= > a = - 5 {x}^{2} {y}^{2} + 7x - 9 - 2 {x}^{2} {y}^{2} + 5x - 7$

$= > a = \: - 7 {x}^{2} {y}^{2} + 12x - 16$
