Factor by grouping: 8x3 - 12x2 + 6x - 9.

8x^3 - 12x^2 + 6x - 9

1. There is no GCF
2. (8x^3 - 12 x^2) + (6x - 9)
3. 4x^2 (2x - 3) + 3 (2x - 3) *** (2x - 3) is the common factor of each group.
4. (4x^2 + 3) (2x - 3)

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

2nd one in the first row is correct
