Answer 1

Respuesta:

17-12axby

Explicación paso a paso:

(3ax-2by)^2

9(ax)^2-12axby+4(by)^2

9(1)-12axby+4(2)

9-12axby+8

17-12axby

Answer 2

Respuesta:

1

Explicación paso a paso:

(3ax+2by) (3ax-2by)=(3ax)^2-(2by)^2

(3ax+2by) (3ax-2by)=9a^2x^2-4b^2y^2

(3ax+2by) (3ax-2by)=9(1)-4(2)

(3ax+2by) (3ax-2by)=9-8=1

Espero que te sirva :3
