Original conversation
User: -2x^2-y^2+xy x=-3 y=5

User: Evaluate the polynomial. -2x^2 - y^2 + xy, when x = -3 and y = 5

Weegy: (-2x - 6)2= -2(x + 3)2= -2y. So, (-2x - 6)2 must equal -2y

-2x^2 - y^2 + xy, x = -3, y = 5:

-2(-3)^2 - (5)^2 + (-3)(5)

= -2(9) - 25 - 15

= -18 - 25 - 15

= -18 - 40

= -58

(-4a^2)^5 = -1,024a^10;
