Question

what is 3s^2+5s+2=0

?????

Answer 1

\[s = -1\]
\[s = - \frac23\]

Answer 2

3s^2+5s + 2 = 0
3s^2 + 3s + 2s + 2 = 0
3s(s+1)+2(s+1) = 0
(s+1)(3s+2)=0
s = -1, -2/3

Answer 3

I hope that helps

Answer 4

Thanks, does the FOIL method work for that then?

Answer 5

I'm not a big fan of FOIL, but if you foil (s+1)(3s+2), you should get back to the original trinomial
