Divide each side by '4'.
-0.25 + -1x + x2 = 0

Move the constant term to the right:

Add '0.25' to each side of the equation.
-0.25 + -1x + 0.25 + x2 = 0 + 0.25

Reorder the terms:
-0.25 + 0.25 + -1x + x2 = 0 + 0.25

Combine like terms: -0.25 + 0.25 = 0.00
0.00 + -1x + x2 = 0 + 0.25
-1x + x2 = 0 + 0.25

Combine like terms: 0 + 0.25 = 0.25
-1x + x2 = 0.25

The x term is -1x.  Take half its coefficient (-0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
-1x + 0.25 + x2 = 0.25 + 0.25

Reorder the terms:
0.25 + -1x + x2 = 0.25 + 0.25

Combine like terms: 0.25 + 0.25 = 0.5
0.25 + -1x + x2 = 0.5

Factor a perfect square on the left side:
(x + -0.5)(x + -0.5) = 0.5

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '0.5' to each side of the equation.
-0.5 + 0.5 + x = 0.707106781 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0
0.0 + x = 0.707106781 + 0.5
x = 0.707106781 + 0.5

Combine like terms: 0.707106781 + 0.5 = 1.207106781
x = 1.207106781

Simplifying
x = 1.207106781

Subproblem 2
x + -0.5 = -0.707106781

Simplifying
x + -0.5 = -0.707106781

Reorder the terms:
-0.5 + x = -0.707106781

Solving
-0.5 + x = -0.707106781

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '0.5' to each side of the equation.
-0.5 + 0.5 + x = -0.707106781 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0
0.0 + x = -0.707106781 + 0.5
x = -0.707106781 + 0.5

Combine like terms: -0.707106781 + 0.5 = -0.207106781
x = -0.207106781
