Question

100x2-20x+1=0 roots by fractorisation
​

Answer 1

Answer:1/10,1/10

Step-by-step explanation:

Answer 2

Answer:

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

if 10x-1=0

x=1/10
