Simplifying
3x + 4 = -1x(x + -6)

Reorder the terms:
4 + 3x = -1x(x + -6)

Reorder the terms:
4 + 3x = -1x(-6 + x)
4 + 3x = (-6 * -1x + x * -1x)
4 + 3x = (6x + -1x2)

Solving
4 + 3x = 6x + -1x2

Solving for variable 'x'.

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

Reorder the terms:
4 + -3x + x2 = 6x + -6x + -1x2 + x2

Combine like terms: 6x + -6x = 0
4 + -3x + x2 = 0 + -1x2 + x2
4 + -3x + x2 = -1x2 + x2

Combine like terms: -1x2 + x2 = 0
4 + -3x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-4' to each side of the equation.
4 + -3x + -4 + x2 = 0 + -4

Reorder the terms:
4 + -4 + -3x + x2 = 0 + -4

Combine like terms: 4 + -4 = 0
0 + -3x + x2 = 0 + -4
-3x + x2 = 0 + -4

Combine like terms: 0 + -4 = -4
-3x + x2 = -4

The x term is -3x.  Take half its coefficient (-1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
-3x + 2.25 + x2 = -4 + 2.25
