​

Answer 1

$\underline{\underline{\bf{\gray{Question}}}}$

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

$\underline{\underline{\bf{\blue{Answer = x²+2xy -y²}}}}$

$\underline{\underline{\bf{\pink{Step\ by\ step\ explanation}}}}$

Let a Should be added x²+ xy + y² to obtain 2x² 3xy

A/Q

${→\sf a +x²+ xy + y² = 2x²+3xy }$

${→\sf a = 2x²+3xy -(x²+ xy + y²) }$

${→\sf a=2x²+3xy-x²-xy-y² }$

${~~~~~\sf a=x²+2xy -y² }$

• x²+2xy -y² Should be added x²+ xy + y² to obtain 2x² 3xy
