Question

what should be added to x2 + xy + y2 to obtain 2x² + 3xy ?


please send me the solutions for this ​

Answer 1

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

$= 2 {x}^{2} + 3xy - {x}^{2} - xy - {y}^{2}$

$= {x }^{2} + 2xy - {y}^{2}$

${x }^{2} + 2xy - {y}^{2} \: \: should \: be \: added$

Answer 2

Answer:

2x²+3xy-x²-y²-xy=x²+2xy-y²

Hope it helps!
