Answer 2

Answer:-

(2) y=1/10=0.1

Step-by-step explanation:-

(2) .

$100 {y}^{2} - 20y + 1 = 0 \\ 100 {y }^{2} - 10y - 10y + 1 = 0 \\ 10y(10y - 1) - 1(10y - 1) = 0 \\ (10y - 1)(10y - 1) = 0 \\ then \: we \: can \: take \: both\\ \: of \: them \: equal\: to \: \: zero \\ 10y - 1 = 0 \\ 10y = 1 \\ y = 1 \div 10 = 0.1$
