Question

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

Answer 1

100x^x -20x +1 = 0

or 100x^x -10x -10x +1 =0

or 10x ( 10x-1) -1 (10x -1) = 0

or (10x-1) (10x-1) = 0

theefore x = 1/10 ; x = 1/10

Answer 2

100X² - 20X + 1 = 0

100X² - 10X - 10X + 1 = 0

10X ( 10X - 1 ) - 1 ( 10X - 1 ) = 0

( 10X - 1 ) ( 10X - 1 ) = 0

( 10X - 1 ) = 0 or ( 10x - 1 ) = 0

x = 1/10 or x = 1 / 10
