Question

(-3x2 + 4xy ) + ( 5x2 - 2xy)
(2xy ) ( - 4x2 - 3) =
(12mn2 + 4mn -8 ) - ( 10mn2 - 2mn -8) =
(4ab + 5) (4ab- 3) =
(5ab2 + 4) (5ab2 - 4) =
(6x2y + 2) (6x2y + 2) =
(3a) (-3a + 4b + 5) =​

Answer 1

Explicación:

1. 2x2+2xy

2. 2xy-4x2 -3

3. 2mn2 + 6mn

4. 16a2b2 -12ab + 20ab -15= 16a2b2 +8ab -15

5. 25a2b4 -20ab2 +20ab2 -16= 25a2b4 -16

6. 36x4y2 + 12x2y + 12x2y + 4= 36x4y2 + 24x2y + 4

7. -9a + 12ab +15a= 6a + 12ab
