Answer 2

Answer:

okk i will answer

Step-by-step explanation:

1. 9x3-6x2-12x  
2. Final result :
3.  3x • (3x2 - 2x - 4)
4. Reformatting the input :
5. Changes made to your input should not affect the solution:
7. (1): "x2"   was replaced by   "x^2".  1 more similar replacement(s).
9. Step by step solution :
10. Step  1  :
11. Equation at the end of step  1  :
12.  ((9 • (x3)) -  (2•3x2)) -  12x
13. Step  2  :
14. Equation at the end of step  2  :
15.  (32x3 -  (2•3x2)) -  12x
16. Step  3  :
17. Step  4  :
18. Pulling out like terms :
19. 4.1     Pull out like factors :
21.   9x3 - 6x2 - 12x  =   3x • (3x2 - 2x - 4)  
23. Trying to factor by splitting the middle term
24. 4.2     Factoring  3x2 - 2x - 4  
26. The first term is,  3x2  its coefficient is  3 .
27. The middle term is,  -2x  its coefficient is  -2 .
28. The last term, "the constant", is  -4  
30. Step-1 : Multiply the coefficient of the first term by the constant   3 • -4 = -12  
32. Step-2 : Find two factors of  -12  whose sum equals the coefficient of the middle term, which is   -2 .
34.      -12    +    1    =    -11  
35.      -6    +    2    =    -4  
36.      -4    +    3    =    -1  
37.      -3    +    4    =    1  
38.      -2    +    6    =    4  
39.      -1    +    12    =    11  
41. Observation : No two such factors can be found !!
42. Conclusion : Trinomial can not be factored
44. Final result :
45.  3x • (3x2 - 2x - 4)
