$3 x^{2} + 3 y^{2} + 4 x y 2 x^{2} + 5 y^{2} - x y - 4 x^{2} - 7 y^{2} - x y \bar{}$

Open in App

Solution

Adding the given expressions:
$3 x^{2} + 3 y^{2} + 4 x y 2 x^{2} + 5 y^{2} - x y - 4 x^{2} - 7 y^{2} - x y \bar{x^{2} + y^{2} + 2 x y}$
Hence, the sum of $3 x^{2} + 3 y^{2} + 4 x y, 2 x^{2} + 5 y^{2} - x y, - 4 x^{2} - 7 y^{2} - x y$ equal to $x^{2} + y^{2} + 2 x y$ .
