Solving
-0.5 + 3x + 5x2 = 0

Solving for variable 'x'.

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

Divide each side by '5'.
-0.1 + 0.6x + x2 = 0

Move the constant term to the right:

Add '0.1' to each side of the equation.
-0.1 + 0.6x + 0.1 + x2 = 0 + 0.1

Reorder the terms:
-0.1 + 0.1 + 0.6x + x2 = 0 + 0.1

Combine like terms: -0.1 + 0.1 = 0.0
0.0 + 0.6x + x2 = 0 + 0.1
0.6x + x2 = 0 + 0.1

Combine like terms: 0 + 0.1 = 0.1
0.6x + x2 = 0.1

The x term is 0.6x.  Take half its coefficient (0.3).
Square it (0.09) and add it to both sides.

Add '0.09' to each side of the equation.
0.6x + 0.09 + x2 = 0.1 + 0.09

Reorder the terms:
0.09 + 0.6x + x2 = 0.1 + 0.09

Combine like terms: 0.1 + 0.09 = 0.19
0.09 + 0.6x + x2 = 0.19

Factor a perfect square on the left side:
(x + 0.3)(x + 0.3) = 0.19

Calculate the square root of the right side: 0.435889894

Break this problem into two subproblems by setting 
(x + 0.3) equal to 0.435889894 and -0.435889894.

Subproblem 1

x + 0.3 = 0.435889894 Simplifying x + 0.3 = 0.435889894 Reorder the terms: 0.3 + x = 0.435889894 Solving 0.3 + x = 0.435889894 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.3' to each side of the equation. 0.3 + -0.3 + x = 0.435889894 + -0.3 Combine like terms: 0.3 + -0.3 = 0.0 0.0 + x = 0.435889894 + -0.3 x = 0.435889894 + -0.3 Combine like terms: 0.435889894 + -0.3 = 0.135889894 x = 0.135889894 Simplifying x = 0.135889894

Subproblem 2

x + 0.3 = -0.435889894 Simplifying x + 0.3 = -0.435889894 Reorder the terms: 0.3 + x = -0.435889894 Solving 0.3 + x = -0.435889894 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.3' to each side of the equation. 0.3 + -0.3 + x = -0.435889894 + -0.3 Combine like terms: 0.3 + -0.3 = 0.0 0.0 + x = -0.435889894 + -0.3 x = -0.435889894 + -0.3 Combine like terms: -0.435889894 + -0.3 = -0.735889894 x = -0.735889894 Simplifying x = -0.735889894
