Question

$3 {x}^{2} - 2x + 5xy -y \: - 8 - 9xy + 3 {x}^{2} - 5x$
please please please help me ​

Answer 1

$(3 {x}^{2} + 3 {x}^{2} ) = (6 {x}^{2} )$

$( - 2x - 5x) = ( - 7x)$

$(5xy - 9xy) = ( - 4xy)$

2 terms r remaining bt they have no pair so

answer will be like

$(6 {x}^{2} - 7x - 4xy - y - 8)$
