Solution for 26=2(x-6)(x+3) equation:


Simplifying
26 = 2(x + -6)(x + 3)

Reorder the terms:
26 = 2(-6 + x)(x + 3)

Reorder the terms:
26 = 2(-6 + x)(3 + x)

Multiply (-6 + x) * (3 + x)
26 = 2(-6(3 + x) + x(3 + x))
26 = 2((3 * -6 + x * -6) + x(3 + x))
26 = 2((-18 + -6x) + x(3 + x))
26 = 2(-18 + -6x + (3 * x + x * x))
26 = 2(-18 + -6x + (3x + x2))

Combine like terms: -6x + 3x = -3x
26 = 2(-18 + -3x + x2)
26 = (-18 * 2 + -3x * 2 + x2 * 2)
26 = (-36 + -6x + 2x2)

Solving
26 = -36 + -6x + 2x2

Solving for variable 'x'.

Combine like terms: 26 + 36 = 62
62 + 6x + -2x2 = -36 + -6x + 2x2 + 36 + 6x + -2x2

Ignore the factor 2.

Subproblem 1

Set the factor '(31 + 3x + -1x2)' equal to zero and attempt to solve: Simplifying 31 + 3x + -1x2 = 0 Solving 31 + 3x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -31 + -3x + x2 = 0 Move the constant term to the right: Add '31' to each side of the equation. -31 + -3x + 31 + x2 = 0 + 31 Reorder the terms: -31 + 31 + -3x + x2 = 0 + 31 Combine like terms: -31 + 31 = 0 0 + -3x + x2 = 0 + 31 -3x + x2 = 0 + 31 Combine like terms: 0 + 31 = 31 -3x + x2 = 31 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 = 31 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 31 + 2.25 Combine like terms: 31 + 2.25 = 33.25 2.25 + -3x + x2 = 33.25 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 33.25 Calculate the square root of the right side: 5.766281297 Break this problem into two subproblems by setting (x + -1.5) equal to 5.766281297 and -5.766281297.

Subproblem 1

x + -1.5 = 5.766281297 Simplifying x + -1.5 = 5.766281297 Reorder the terms: -1.5 + x = 5.766281297 Solving -1.5 + x = 5.766281297 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = 5.766281297 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 5.766281297 + 1.5 x = 5.766281297 + 1.5 Combine like terms: 5.766281297 + 1.5 = 7.266281297 x = 7.266281297 Simplifying x = 7.266281297

Subproblem 2

x + -1.5 = -5.766281297 Simplifying x + -1.5 = -5.766281297 Reorder the terms: -1.5 + x = -5.766281297 Solving -1.5 + x = -5.766281297 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = -5.766281297 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -5.766281297 + 1.5 x = -5.766281297 + 1.5 Combine like terms: -5.766281297 + 1.5 = -4.266281297 x = -4.266281297 Simplifying x = -4.266281297
