Answer 2

Given :-

$100x {}^{2} - 20x + 1 = 0$

What to find out =Roots of the equation?

Solution :-

Factorise by splitting middle term

$100 {x}^{2} - 20x + 1 = 0 \\ \\ 100 {x}^{2} - 10x - 10x + 1 = 0 \\ \\ 10x(10x - 1) - 1(10x - 1) = 0 \\ \\ (10x - 1) (10x - 1) = 0 \\ \\ (10x - 1) { }^{2} = 0$

Hence,

$x = \frac{1}{10} \: \: \: \: \: ans$

Extra information :-
