It can be factored as the SQUARE OF A BINOMIAL
16m-28m factored = -12
66 factored to get -1 = 65
273-8 factored = 265
109 = 109
We factored many suggestions into the equation.
If a number cannot be factored it is a prime number.
Factored loads are inflated loads. Each type of load has a specific safety factor (load factor) added. Un-factored loads are not inflated.
You can't know if a general polynomial is in factored form.
a3-4a = a(a2-4) when factored
3y-6y in factored form = -3
27-y3 factored completely = 24
