Reorder the terms:
-4 + x = 4x2

Solving
-4 + x = 4x2

Solving for variable 'x'.

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

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

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

Move the constant term to the right:

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

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

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

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

The x term is x.  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.
-0.25x + 0.25 + x2 = -1 + 0.25
