Answer 1

Heya..!!

Here's your answer...

_______________________________________
$9 {x}^{2} - 2xy - 3 {x}^{2} + 5xy \\ 6 {x}^{2} + 3xy \\ \\ now \: 3 {x}^{2} + 2xy - 6 {x}^{2} + 3xy \\ - 3 {x}^{2} + 5xy$

Hey there!
Down here ⏬

Sum

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

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

{ 9+(-3) ; (-2)+5 }

$6x {}^{2} + 3xy$

Difference

$(6x {}^{2} + 3xy) - (3x {}^{2} + 2xy)$

$6x {}^{2} + 3xy - 3x {}^{2} - 2xy$

{ 6+(-2); 3-2 }

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