(xy + 3)(xy - 4)(x + 1)(x + 3) + x(x - 4)(2x + 1)(x - 2)( + x(x + 3)(x + 2)(x - 4) - x(x - 2)Gracias?

(xy + 3)(xy - 4) (x + 1)(x + 3) + x(x - 4) (2x + 1)(x - 2)( + x(x + 3) (x + 2)(x - 4) - x(x - 2) Gracias.

En resumen

(xy + 3)(xy - 4) = xy ^ 2 - xy - 12 (x + 1)(x + 3) + x(x - 4) = 2x ^ 2 + 3 (2x + 1)(x - 2) + x(x + 3) = 3x ^ 2 - 2 (x + 2)(x - 4) - x(x - 2) = - 8.

(xy + 3)(xy - 4) = xy ^ 2 - xy - 12

(x + 1)(x + 3) + x(x - 4) = 2x ^ 2 + 3

(2x + 1)(x - 2) + x(x + 3) = 3x ^ 2 - 2

(x + 2)(x - 4) - x(x - 2) = - 8.
