find zero and verify relationship between the zero and coefficients
4S²-4S+1
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= 0
⇒s = 1/2, 1/2
sum of the zeroes = 1/2 + 1/2 = -(co-efficient of s) /(co-efficient of s²)
=2/2 = 4/4
= 1=1
product of the zeroes = 1/2(1/2) = constant term / coefficient of s²
= 1/4= 1/4
