I think so.r2 + 7r + 6 = [ (r+6) (r+1) ]
r2+6r-7 = (r+7)(r-1) when factored
(r+5)(r-4) The idea is to get two numbers whose product in this case is -20, and whose sum in this case s +1.
7(r-12) A 7 is taken out because it is a common factor to both terms.
If you mean: 5x+35 then when factored it is 5(x+7)
66 factored to get -1 = 65
273-8 factored = 265
It can be factored as the SQUARE OF A BINOMIAL
16m-28m factored = -12
Factored loads are inflated loads. Each type of load has a specific safety factor (load factor) added. Un-factored loads are not inflated.
