Which is equivalent to the following expression? (2x^2+4xy-y^2)+(x^2+3xy-y^2)

Karo-lina-s [1.5K]

Answer C : 3x^2+7xy-2y^2

equivalent to the following expression

$(2x^2+4xy-y^2)+(x^2+3xy-y^2)$

$2x^2+4xy-y^2+x^2+3xy-y^2$

Combine like terms

$2x^2+x^2+4xy+3xy-y^2-y^2$

2x^2 + x^2 is 3x^2

4xy+3xy is 7xy

-y^2-y^2 is -2y^2

So expression becomes

$3x^2+7xy-2y^2$

Answer C is correct
