User: The question just says, evaluate the polynomial. -2x^2-y^2+xy, when x=-3 and y=5.

Weegy: x2+ 2y2- 3xy = 3^2 + 2*4^2 - 3*3*4 = 9+32-36 = 5

User: That isn't one of the answers. The answers for this are -58, 28, -28, -8.

-2x^2 - y^2 + xy, when x =- 3 and y = 5

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

= -2(9) - 25 - 15

= -18 - 25 - 15

= -43 - 15

= -58

-2^2-y^2+xy, when x=-3 and y=5

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

= -4 - 25 - 15

= -29 - 15

= -44
Factor: x^2-25 Factor: 9x^2-4y^2
Weegy: Is there an = in this equation anywhere? (More)

x^2 - 25 = (x - 5)(x + 5)

9x^2 - 4y^2 = (3x - 2y)(3x + 2y)
