Answer 2

Answer:

$8$

Step-by-step explanation:

• Given expression:

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

• To solve the given expression, we need to apply the values of $x, y$

• On substituting the values of $x,y$, we get

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

$=2(0^{2} )+2(-2^{2} )-(0)(-2)$

$=2(0)+2(4)-0$

$=0+8-0$

$=8$

Hence, the value of the expression is $8$.
