5 + 3x = (6 + -14x + 4x2)

Solving
5 + 3x = 6 + -14x + 4x2

Solving for variable 'x'.

Reorder the terms:
5 + -6 + 3x + 14x + -4x2 = 6 + -14x + 4x2 + -6 + 14x + -4x2

Combine like terms: 5 + -6 = -1
-1 + 3x + 14x + -4x2 = 6 + -14x + 4x2 + -6 + 14x + -4x2

Combine like terms: 3x + 14x = 17x
-1 + 17x + -4x2 = 6 + -14x + 4x2 + -6 + 14x + -4x2

-1 + 17x + -4x2 = 6 + -6 + -14x + 14x + 4x2 + -4x2

Combine like terms: 6 + -6 = 0
-1 + 17x + -4x2 = 0 + -14x + 14x + 4x2 + -4x2
-1 + 17x + -4x2 = -14x + 14x + 4x2 + -4x2

Combine like terms: -14x + 14x = 0
-1 + 17x + -4x2 = 0 + 4x2 + -4x2
-1 + 17x + -4x2 = 4x2 + -4x2

Combine like terms: 4x2 + -4x2 = 0
-1 + 17x + -4x2 = 0

Begin completing the square.  Divide all terms by
-4 the coefficient of the squared term: 

Divide each side by '-4'.
0.25 + -4.25x + x2 = 0

Move the constant term to the right:

Add '-0.25' to each side of the equation.
0.25 + -4.25x + -0.25 + x2 = 0 + -0.25

Reorder the terms:
0.25 + -0.25 + -4.25x + x2 = 0 + -0.25

Combine like terms: 0.25 + -0.25 = 0.00
0.00 + -4.25x + x2 = 0 + -0.25
-4.25x + x2 = 0 + -0.25

Combine like terms: 0 + -0.25 = -0.25
-4.25x + x2 = -0.25

The x term is -4.25x.  Take half its coefficient (-2.125).
Square it (4.515625) and add it to both sides.

Add '4.515625' to each side of the equation.
-4.25x + 4.515625 + x2 = -0.25 + 4.515625

Reorder the terms:
4.515625 + -4.25x + x2 = -0.25 + 4.515625

Combine like terms: -0.25 + 4.515625 = 4.265625
4.515625 + -4.25x + x2 = 4.265625
