Add '0.00000625' to each side of the equation.
0.005x + 0.00000625 + x2 = 0.0005 + 0.00000625

Reorder the terms:
0.00000625 + 0.005x + x2 = 0.0005 + 0.00000625

Combine like terms: 0.0005 + 0.00000625 = 0.00050625
0.00000625 + 0.005x + x2 = 0.00050625

Factor a perfect square on the left side:
(x + 0.0025)(x + 0.0025) = 0.00050625

Calculate the square root of the right side: 0.0225

Break this problem into two subproblems by setting 
(x + 0.0025) equal to 0.0225 and -0.0225.

Subproblem 1

x + 0.0025 = 0.0225 Simplifying x + 0.0025 = 0.0225 Reorder the terms: 0.0025 + x = 0.0225 Solving 0.0025 + x = 0.0225 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.0025' to each side of the equation. 0.0025 + -0.0025 + x = 0.0225 + -0.0025 Combine like terms: 0.0025 + -0.0025 = 0.0000 0.0000 + x = 0.0225 + -0.0025 x = 0.0225 + -0.0025 Combine like terms: 0.0225 + -0.0025 = 0.02 x = 0.02 Simplifying x = 0.02

Subproblem 2

x + 0.0025 = -0.0225 Simplifying x + 0.0025 = -0.0225 Reorder the terms: 0.0025 + x = -0.0225 Solving 0.0025 + x = -0.0225 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.0025' to each side of the equation. 0.0025 + -0.0025 + x = -0.0225 + -0.0025 Combine like terms: 0.0025 + -0.0025 = 0.0000 0.0000 + x = -0.0225 + -0.0025 x = -0.0225 + -0.0025 Combine like terms: -0.0225 + -0.0025 = -0.025 x = -0.025 Simplifying x = -0.025

Solution

The solution to the problem is based on the solutions from the subproblems. x = {0.02, -0.025}
