Simplifying
(x + 2)(x + -3) = 4

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

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

Multiply (2 + x) * (-3 + x)
(2(-3 + x) + x(-3 + x)) = 4
((-3 * 2 + x * 2) + x(-3 + x)) = 4
((-6 + 2x) + x(-3 + x)) = 4
(-6 + 2x + (-3 * x + x * x)) = 4
(-6 + 2x + (-3x + x2)) = 4

Combine like terms: 2x + -3x = -1x
(-6 + -1x + x2) = 4

Solving
-6 + -1x + x2 = 4

Solving for variable 'x'.

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

-10 + -1x + x2 = 4 + -4

Combine like terms: 4 + -4 = 0
-10 + -1x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '10' to each side of the equation.
-10 + -1x + 10 + x2 = 0 + 10

Reorder the terms:
-10 + 10 + -1x + x2 = 0 + 10

Combine like terms: -10 + 10 = 0
0 + -1x + x2 = 0 + 10
-1x + x2 = 0 + 10

Combine like terms: 0 + 10 = 10
-1x + x2 = 10

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 = 10 + 0.25

Reorder the terms:
0.25 + -1x + x2 = 10 + 0.25

Combine like terms: 10 + 0.25 = 10.25
0.25 + -1x + x2 = 10.25
