thanks for asking the question i hope this helps

Answer 2

Given equations are,

$6x^{2} -4xy+5y^{2}$

$8y^{2} +6xy-3x^{2}$

$5x^{2} -3xy-4y^{2}$

Now we have to add the three equations.

By adding the three equations we get,

$6x^{2} -4xy+5y^{2} +8y^{2} +6xy-3x^{2} +5x^{2} -3xy-4y^{2}$

Write, all the $x^{2}$ together, all the $y^{2}$ terms together and all the $xy$ terms together.

$6x^{2} +5x^{2}-3x^{2} +5y^{2} +8y^{2}-4y^{2} +6xy -4xy-3xy$

$11x^{2} -3x^{2} +13y^{2} -4y^{2} +6xy-7xy$

$8x^{2} +9y^{2} -xy$

Therefore, the final answer after adding is $8x^{2} +9y^{2} -xy$
