Could you please help me factor the trinomial.
s^27s+12

Math 
tchrwill,
s^27s+12
Since the coefficient of s^2 is 1, the factors are of the form (s+/?)(s+/?)
What two numbers have a sum of 7 and a product of 12?
Clearly, 3 and 4.
SInce the sum is 7 and the product is +12, the only possibility is (s  3)(s  4)
