Tolong bantu ya kak...hari senin dikumpulkan ​

Answer 1

Penjelasan dengan langkah-langkah:

11. 3x - 12 = 3( x - 4)

12. 2xy - 12y = 2y( x - 6)

13. 4x + 10x^2y = 2x ( 2 + 5xy)

14. -9a^2b^2 + 21a^2b^3 = -3a^2b^2(3 - 7b)

15.

= 1/2 a^2 b^2 ( 1/2a + b)

16. x^2 - 9 = (x+3)(x-3)

17. 4x^2 - 36 = (2x + 6)(2x - 6)

18. 25x^2 - y^2 = (5x + y)(5x - y)

19. 16a^2 - 49b^2 = (4a + 7b)(4a - 7b)

20. 5x^2 - 20y^2 = 5(x + 2)(x - 2)
