Question

Actividad 1: En una hoja blanca o en una hoja de cuaderno resuelve las siguientes
multiplicaciones:
(3X) (2X) =
( 2a + 1)(2a +2 ) =
(6Y) (44) =
(2x - 3) (3x + 2) =
(4a) (a) =
( 5y + 4) (3y -4)=
(7b ) ( 2b ) =
( x + y ) ( x-Y) =
(5c ) ( 8c) =
( 2x + 3)(2x + 5 ) =​

Answer 1

Respuesta:

(3x) (2x) = 6x

(2a + 1) (2a + 2)= 4a + 2

(6Y) (44) = 264Y

(2x - 3) (3x + 2) = 6x - 6

(4a) (a) = 5a

(5y + 4) (3y - 4) = 15y - 16

(7b) (2b) = 14b

(x + y) (x-y) = 2x - 2y

(5c) (8c) = 40c

(2x + 3) (2x + 5) = 4x + 15
