(0.01x + x^2) / (0.01 – x) = 0

multiply the fraction by (0.01 – x) and the 0 by (0.01 – x) [to get rid of the denominator]

hence

(0.01x + x^2) = 0

or

x^2 + 0.01x = 0

now you can use the quadratic formula (where b = 0.01 , a = 1, and c = 0)

hope i helped!!

x(x+0.01)/(0.01-x) = 0.12

Expand numerator and multiply both sides of equation by (0.01-x):

x² + 0.01x = 0.0012 – 0.12x

x² + 0.13x – 0.0012 = 0

Now you can use the formula.
