Solution for 36=2(x-3)(x-3) equation:


Simplifying
36 = 2(x + -3)(x + -3)

Reorder the terms:
36 = 2(-3 + x)(x + -3)

Reorder the terms:
36 = 2(-3 + x)(-3 + x)

Multiply (-3 + x) * (-3 + x)
36 = 2(-3(-3 + x) + x(-3 + x))
36 = 2((-3 * -3 + x * -3) + x(-3 + x))
36 = 2((9 + -3x) + x(-3 + x))
36 = 2(9 + -3x + (-3 * x + x * x))
36 = 2(9 + -3x + (-3x + x2))

Combine like terms: -3x + -3x = -6x
36 = 2(9 + -6x + x2)
36 = (9 * 2 + -6x * 2 + x2 * 2)
36 = (18 + -12x + 2x2)

Solving
36 = 18 + -12x + 2x2

Solving for variable 'x'.

Combine like terms: 36 + -18 = 18
18 + 12x + -2x2 = 18 + -12x + 2x2 + -18 + 12x + -2x2

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

Combine like terms: 18 + -18 = 0
18 + 12x + -2x2 = 0 + -12x + 12x + 2x2 + -2x2
18 + 12x + -2x2 = -12x + 12x + 2x2 + -2x2

Combine like terms: -12x + 12x = 0
18 + 12x + -2x2 = 0 + 2x2 + -2x2
18 + 12x + -2x2 = 2x2 + -2x2

Combine like terms: 2x2 + -2x2 = 0
18 + 12x + -2x2 = 0

Factor out the Greatest Common Factor (GCF), '2'.
2(9 + 6x + -1x2) = 0

Ignore the factor 2.

Subproblem 1

Set the factor '(9 + 6x + -1x2)' equal to zero and attempt to solve: Simplifying 9 + 6x + -1x2 = 0 Solving 9 + 6x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -9 + -6x + x2 = 0 Move the constant term to the right: Add '9' to each side of the equation. -9 + -6x + 9 + x2 = 0 + 9 Reorder the terms: -9 + 9 + -6x + x2 = 0 + 9 Combine like terms: -9 + 9 = 0 0 + -6x + x2 = 0 + 9 -6x + x2 = 0 + 9 Combine like terms: 0 + 9 = 9 -6x + x2 = 9 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 = 9 + 9 Reorder the terms: 9 + -6x + x2 = 9 + 9 Combine like terms: 9 + 9 = 18 9 + -6x + x2 = 18 Factor a perfect square on the left side: (x + -3)(x + -3) = 18 Calculate the square root of the right side: 4.242640687 Break this problem into two subproblems by setting (x + -3) equal to 4.242640687 and -4.242640687.

Subproblem 1

x + -3 = 4.242640687 Simplifying x + -3 = 4.242640687 Reorder the terms: -3 + x = 4.242640687 Solving -3 + x = 4.242640687 Solving for variable 'x'.
