Answer 2

Answer:

${ - 14x}^{2} - 25xy + 26$

Step-by-step explanation:

1st equations

$({6x}^{2} + 9xy - 11 )+ ( {3x}^{2} + 4xy + 14$

${9x}^{2} + 13xy + 3$

2nd equation

$( {3x}^{2} - 7xy + 21) + ( - {8x}^{2} - 5xy + 8)$

$( {3x}^{2} - 7xy + 21 - {8x}^{2} - 5xy + 8)$

$- {5x}^{2} - 12xy + 29$

now,A/Q

$( { - 5x}^{2} - 12xy + 29) - ( {9x}^{2} + 13xy + 3)$

${ - 5x}^{2} - 12xy + 29 - {9x}^{2} - 13xy - 3$

${ - 14x}^{2} - 25xy + 26$
