(5x^7 - 16x^5 - 11) - (-11x^5 + 9x^7 - 14)

= -4x^7 - 5x^5 + 3

= -4x^7 - 5x^5 + 3

(9m + 10)^2;

(9m + 10)(9m + 10);

81m^2 + 90m + 90m + 100

= 81m^2 + 180 + 100

(9m + 10)(9m + 10);

81m^2 + 90m + 90m + 100

= 81m^2 + 180 + 100

-12y - 8x - 4x = -12y - 12x

x^2 - 4y^2 - xy, when x = 2, y = -2;

(2)^2 - 4(-2)^2 - (2)(-2);

4 - 4(4) - (-4);

4 - 16 + 4

-12 + 4 = -8

(2)^2 - 4(-2)^2 - (2)(-2);

4 - 4(4) - (-4);

4 - 16 + 4

-12 + 4 = -8
