This is a way to factoring trinomials (there exist different equivalent methods).
Multiply the trinomial but the term accompanying . This is the second line. Then, you could take the square of the 
, ant try to create a factor () () that will correspond to the expression in the second line. That is, we want 
In ? we put the corresponding numbers that, if we multiply them we will obtain 42, and if we add them we will obtain 13. This numbers are 6 and 7. Then, we have 
The last step is divide by the number that we multipy in the first step.
Answer:
commission on the purchase = $559
gross cost = $9371
Step-by-step explanation:
Given data
Prime Cost = $8,600
Commission Rate = 6.5%
Local Delivery = 44
storage = 77
air freight = 91
to find out
Luis' commission on the purchase and the gross cost
solution
we find first commission on the purchase that is = commision @ 6.5%
commission on the purchase = 8600 × 0.065 = $559
commission on the purchase = $559
and
gross cost = Prime Cost + Commission + Local Delivery +storage +air freight
gross cost = 8600 + 559 + 44+ 77 + 91
gross cost = $9371
