Answer 2

1. (5X)² - 7(5X)+10/5=(5X-2)(5X-5)/5= (5X-2)(X-1)
2. (2X)² -5(2X)+6/2= (2X-6)(2X+1)/2= (X-3)(2X+1)
3. (X+5)(X-3)
4. (X-6)(X+2)
5. (2X)² + 1(2X)-12/2= (2X+4)(2X- 3)/2=(X+2)(2X-3)
6. (3X)² - 11(3X) +18/3= (3X-9)(3X-2)/3=(X-3) (3X-2)
7. (4X)²- 7(4X) +12/ 4= (4X-4)(4X-3)/4 =(X-1)(4X-3)
8. (2X)² -4 (2X) + 3= (2X-3)(2X-1)
9. (X-5)(X-4)
10. (5X)² +9(5X) - 20/5=(5X-5)(5X-4)/5= (X-1)(5X-4)
11. (7X)²- 5(7X)-14/7=(7X-7)(7X+2)/7=(X-1)(7X+2)
12. (4X)² -17(4X)+60/4=(4X-12)(4X-5)/4=(X-3)(4X-5)
