Solving
2 + -50x + 312.5x2 = 0

Solving for variable 'x'.

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

Divide each side by '312.5'.
0.0064 + -0.16x + x2 = 0

Move the constant term to the right:

Add '-0.0064' to each side of the equation.
0.0064 + -0.16x + -0.0064 + x2 = 0 + -0.0064

Reorder the terms:
0.0064 + -0.0064 + -0.16x + x2 = 0 + -0.0064

Combine like terms: 0.0064 + -0.0064 = 0.0000
0.0000 + -0.16x + x2 = 0 + -0.0064
-0.16x + x2 = 0 + -0.0064

Combine like terms: 0 + -0.0064 = -0.0064
-0.16x + x2 = -0.0064

The x term is -0.16x.  Take half its coefficient (-0.08).
Square it (0.0064) and add it to both sides.

Add '0.0064' to each side of the equation.
-0.16x + 0.0064 + x2 = -0.0064 + 0.0064

Reorder the terms:
0.0064 + -0.16x + x2 = -0.0064 + 0.0064

Combine like terms: -0.0064 + 0.0064 = 0.0000
0.0064 + -0.16x + x2 = 0.0000

Factor a perfect square on the left side:
(x + -0.08)(x + -0.08) = 0.0000

Calculate the square root of the right side: 0.0000

Break this problem into two subproblems by setting 
(x + -0.08) equal to 0.0000 and 0.0000.

Subproblem 1

x + -0.08 = 0.0000 Simplifying x + -0.08 = 0.0000 Reorder the terms: -0.08 + x = 0.0000 Solving -0.08 + x = 0.0000 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.08' to each side of the equation. -0.08 + 0.08 + x = 0.0000 + 0.08 Combine like terms: -0.08 + 0.08 = 0.00 0.00 + x = 0.0000 + 0.08 x = 0.0000 + 0.08 Combine like terms: 0.0000 + 0.08 = 0.08 x = 0.08 Simplifying x = 0.08

Subproblem 2

x + -0.08 = 0.0000 Simplifying x + -0.08 = 0.0000 Reorder the terms: -0.08 + x = 0.0000 Solving -0.08 + x = 0.0000 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.08' to each side of the equation. -0.08 + 0.08 + x = 0.0000 + 0.08 Combine like terms: -0.08 + 0.08 = 0.00 0.00 + x = 0.0000 + 0.08 x = 0.0000 + 0.08 Combine like terms: 0.0000 + 0.08 = 0.08 x = 0.08 Simplifying x = 0.08

Solution

The solution to the problem is based on the solutions from the subproblems. x = {0.08, 0.08}
