If this is 4s2 - 4s + 1 then:

 

The coefficients of the polynomial are 4, -4 and 1.

 

Because it can be written as (2s - 1)2 there are two, i.e. repeated zeros, both at s = 1/2 

 

 

If it is 4s2 -4(s+1) then:

 

The polynomial is 4s2 - 4s - 4 with coefficients 4, -4 and -4.

 

It doesn't factor so it's zeros are:

 

4×s24×s4=0{s=(51)2s=(5+1)2}{s=0.6180339887498948s=1.6180339887498948}
