Question 598991
You didn't say what you want to do with these.
Factor them?
What do you mean by "backwards?"
---------------
4m^2-18m+14
All the coefficients are even, 2 is a factor.
= 2*(2m^2 - 9m + 7)
It will have to be (m + ??)*(2m + ??), or 
(m + a)*(2m + b)
a & b have to be 1 & 7, the only factors of 7.
The product a*b is positive, so a & b have the same sign.
The m term is negative, so a & b are negative.
-----
Only 2 possibilities:
(m - 1)*(2m - 7) or (m - 7)*(2m - 1)
------
--> 2(m - 1)(2m - 7)
========================
15m^3+24m^2+9m
All coeff's divisible by 3
-------------
15m^2-10m-25 *** Factor of 5
------
50m^3-2m *** Factor of 2m
------
3m^2-10m+8
Similar to the first one.
------
60m^3+54m^2-6m *** Factor of 6m
