Step-by-step explanation: 4s² – 4s +1 =0 4s² -2s-2s +1=0 2s( 2s -1) -1(2s-1) =0 (2s-1) (2s -1) =0 2s – 1 =0 2s= 1 s = 1/2 Reply
Step-by-step explanation:
4s² – 4s +1 =0
4s² -2s-2s +1=0
2s( 2s -1) -1(2s-1) =0
(2s-1) (2s -1) =0
2s – 1 =0
2s= 1
s = 1/2
4s²-4s+1
4s²-2s-2s+1
2s(2s-1)-1(2s-1)
(2s-1) (2s-1)
