Trying to factor by splitting the middle term
4.1 Factoring 6m2-5m+4
The first term is, 6m2 its coefficient is 6 .
The middle term is, -5m its coefficient is -5 .
The last term, "the constant", is +4
Step-1 : Multiply the coefficient of the first term by the constant 6 • 4 = 24
Step-2 : Find two factors of 24 whose sum equals the coefficient of the middle term, which is -5 .
-24 + -1 = -25
-12 + -2 = -14
-8 + -3 = -11
-6 + -4 = -10
-4 + -6 = -10
-3 + -8 = -11
-2 + -12 = -14
-1 + -24 = -25
1 + 24 = 25
2 + 12 = 14
3 + 8 = 11
4 + 6 = 10
6 + 4 = 10
8 + 3 = 11
12 + 2 = 14
24 + 1 = 25
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored

:
Checking for a perfect cube
5.1 14m3-7m2+12m-9 is not a perfect cube
Trying to factor by pulling out :
5.2 Factoring: 14m3-7m2+12m-9
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 12m-9
Group 2: 14m3-7m2
