Simplifying
(x + -6)(x + -3) = 10000

Reorder the terms:
(-6 + x)(x + -3) = 10000

Reorder the terms:
(-6 + x)(-3 + x) = 10000

Multiply (-6 + x) * (-3 + x)
(-6(-3 + x) + x(-3 + x)) = 10000
((-3 * -6 + x * -6) + x(-3 + x)) = 10000
((18 + -6x) + x(-3 + x)) = 10000
(18 + -6x + (-3 * x + x * x)) = 10000
(18 + -6x + (-3x + x2)) = 10000

Combine like terms: -6x + -3x = -9x
(18 + -9x + x2) = 10000

Solving
18 + -9x + x2 = 10000

Solving for variable 'x'.

18 + -10000 + -9x + x2 = 10000 + -10000

Combine like terms: 18 + -10000 = -9982
-9982 + -9x + x2 = 10000 + -10000

Combine like terms: 10000 + -10000 = 0
-9982 + -9x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '9982' to each side of the equation.
-9982 + -9x + 9982 + x2 = 0 + 9982

Reorder the terms:
-9982 + 9982 + -9x + x2 = 0 + 9982

Combine like terms: -9982 + 9982 = 0
0 + -9x + x2 = 0 + 9982
-9x + x2 = 0 + 9982

Combine like terms: 0 + 9982 = 9982
-9x + x2 = 9982

The x term is -9x.  Take half its coefficient (-4.5).
Square it (20.25) and add it to both sides.

Add '20.25' to each side of the equation.
-9x + 20.25 + x2 = 9982 + 20.25

Reorder the terms:
20.25 + -9x + x2 = 9982 + 20.25

Combine like terms: 9982 + 20.25 = 10002.25
20.25 + -9x + x2 = 10002.25
