Solution for 0.08r^2-0.02r+0.01=0 equation:


Simplifying
0.08r2 + -0.02r + 0.01 = 0

Reorder the terms:
0.01 + -0.02r + 0.08r2 = 0

Solving
0.01 + -0.02r + 0.08r2 = 0

Solving for variable 'r'.

Begin completing the square.  Divide all terms by
0.08 the coefficient of the squared term: 

Divide each side by '0.08'.
0.125 + -0.25r + r2 = 0

Move the constant term to the right:

Add '-0.125' to each side of the equation.
0.125 + -0.25r + -0.125 + r2 = 0 + -0.125

Reorder the terms:
0.125 + -0.125 + -0.25r + r2 = 0 + -0.125

Combine like terms: 0.125 + -0.125 = 0.000
0.000 + -0.25r + r2 = 0 + -0.125
-0.25r + r2 = 0 + -0.125

Combine like terms: 0 + -0.125 = -0.125
-0.25r + r2 = -0.125

The r term is -0.25r.  Take half its coefficient (-0.125).
Square it (0.015625) and add it to both sides.

Add '0.015625' to each side of the equation.
-0.25r + 0.015625 + r2 = -0.125 + 0.015625

Reorder the terms:
0.015625 + -0.25r + r2 = -0.125 + 0.015625

Combine like terms: -0.125 + 0.015625 = -0.109375
0.015625 + -0.25r + r2 = -0.109375

Factor a perfect square on the left side:
(r + -0.125)(r + -0.125) = -0.109375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
