s^2-8s-33
I assume you mean: s² - 8s - 33

let s² - 8s - 33 = 0

factorise,

s...........-11..........-11s
s...........+3............+3s
________________
s²..........-33...........-8s

therefore (s - 11)(s + 3) = 0

s - 11 = 0..........or.........s + 3 = 0
s = 11................or.............. = -3

(s - 11).(s + 3)
Check
s.(s + 3) - 11.(s + 3)
sÂ² + 3s - 11s - 33
sÂ² - 8s - 33 (as required)
