2(x-3)(x-3)=12

Solution for 2(x-3)(x-3)=12 equation:

Simplifying
2(x + -3)(x + -3) = 12

Reorder the terms:
2(-3 + x)(x + -3) = 12

Reorder the terms:
2(-3 + x)(-3 + x) = 12

Multiply (-3 + x) * (-3 + x)
2(-3(-3 + x) + x(-3 + x)) = 12
2((-3 * -3 + x * -3) + x(-3 + x)) = 12
2((9 + -3x) + x(-3 + x)) = 12
2(9 + -3x + (-3 * x + x * x)) = 12
2(9 + -3x + (-3x + x2)) = 12

Combine like terms: -3x + -3x = -6x
2(9 + -6x + x2) = 12
(9 * 2 + -6x * 2 + x2 * 2) = 12
(18 + -12x + 2x2) = 12

Solving
18 + -12x + 2x2 = 12

Solving for variable 'x'.

Reorder the terms:
18 + -12 + -12x + 2x2 = 12 + -12

Combine like terms: 18 + -12 = 6
6 + -12x + 2x2 = 12 + -12

Combine like terms: 12 + -12 = 0
6 + -12x + 2x2 = 0

Subproblem 1
Set the factor '(3 + -6x + x2)' equal to zero and attempt to solve:

Simplifying
3 + -6x + x2 = 0

Solving
3 + -6x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-3' to each side of the equation.
3 + -6x + -3 + x2 = 0 + -3

Reorder the terms:
3 + -3 + -6x + x2 = 0 + -3

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

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

The x term is -6x.  Take half its coefficient (-3).
Square it (9) and add it to both sides.

Add '9' to each side of the equation.
-6x + 9 + x2 = -3 + 9

Reorder the terms:
9 + -6x + x2 = -3 + 9

Combine like terms: -3 + 9 = 6
9 + -6x + x2 = 6

Factor a perfect square on the left side:
(x + -3)(x + -3) = 6

Calculate the square root of the right side: 2.449489743
