Step-by-step explanation:

Answer 2

Answer: 1/10 or 0.1  [equal real roots]

Step-by-step explanation:

x^2 - x/5 + 1/100 = 0

sum = -1/5

product = 1/100

The numbers are -1/10 , -1/10     [sum = -2/10=-1/5 && product=1/100]

x^2 - x/10 - x/10 + 1/100 = 0

x(x- 1/10) - 1/10 *(x - 1/10) = 0

[x - 1/10] [x - 1/10] = 0

x = 1/10 or 0.1

ALTERNATE:

100x^2 - 20x + 1 = 0                [LCM is '100']

sum = -20 && product = 100

The numbers are -10,-10

100x^2 - 10x - 10x + 1 = 0

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

[10x-1][10x-1] = 0

10x =1

x=1/10 = 0.1
