You can put this solution on YOUR website! Factor the trinomial
s^2-9s+18
---
Think of two numbers whose
product = 18
sum = -9
------
The numbers are -6 and -3
-------
Substitute for the middle term of the quadratic to get:
s^2 - 6s-3s + 18
----
Factor by groups:
s(s-6)-3(s-6)
Factor Again to get the final answer:
(s-6)(s-3)
