Question 582099
Does anyone have a easy way to factor?  Her is a problem I just don't know how to do.

9ax^3+15ax^2-14ax
-------------------
There is no easy way.  You find the combination that works.
------
In this one, all 3 terms have an a & and x.  Factor those out 1st.
That leaves 9x^2 + 15x - 14
------
It'll be
(ax + b)*(cx + d)
a*b = 9, so that's either 1*9 or 3*3
b*d = 14, so that's either 1*14 or 2*7 with different signs (one +, one minus)
Then you find a combination that gives +15x
