-18 + x + -4x2 = 0

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

Divide each side by '-4'.
4.5 + -0.25x + x2 = 0

Move the constant term to the right:

Add '-4.5' to each side of the equation.
4.5 + -0.25x + -4.5 + x2 = 0 + -4.5

Reorder the terms:
4.5 + -4.5 + -0.25x + x2 = 0 + -4.5

Combine like terms: 4.5 + -4.5 = 0.0
0.0 + -0.25x + x2 = 0 + -4.5
-0.25x + x2 = 0 + -4.5

Combine like terms: 0 + -4.5 = -4.5
-0.25x + x2 = -4.5

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 = -4.5 + 0.25

Reorder the terms:
0.25 + -0.25x + x2 = -4.5 + 0.25

Combine like terms: -4.5 + 0.25 = -4.25
0.25 + -0.25x + x2 = -4.25

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = -4.25

Can't calculate square root of the right side.

The solution to this equation could not be determined.
