This is a hard one to factor but it can be done with a bit of trial & error:
The factors of 135 are:
1 X 135 = 135
3 X 45 = 135
5 X 27 = 135
9 X 15 = 135
The factors of 91 are:
1 X 91 = 91
7 X 13 = 91
You can try various combinations of these but the sum (or the difference) of the factors for the x-term must equal -222.
For example:
To find the roots, we must have an equation, so you can set the expression equal to zero.
Factor.
Apply the zero products principle.

If then and
If then and
The factors are: (15x - 13) and (9x - 7)
The roots are: and
