Solution for 5=(x+3)(x+3) equation:


Simplifying
5 = (x + 3)(x + 3)

Reorder the terms:
5 = (3 + x)(x + 3)

Reorder the terms:
5 = (3 + x)(3 + x)

Multiply (3 + x) * (3 + x)
5 = (3(3 + x) + x(3 + x))
5 = ((3 * 3 + x * 3) + x(3 + x))
5 = ((9 + 3x) + x(3 + x))
5 = (9 + 3x + (3 * x + x * x))
5 = (9 + 3x + (3x + x2))

Combine like terms: 3x + 3x = 6x
5 = (9 + 6x + x2)

Solving
5 = 9 + 6x + x2

Solving for variable 'x'.

Combine like terms: 5 + -9 = -4
-4 + -6x + -1x2 = 9 + 6x + x2 + -9 + -6x + -1x2

Reorder the terms:
-4 + -6x + -1x2 = 9 + -9 + 6x + -6x + x2 + -1x2

Combine like terms: 9 + -9 = 0
-4 + -6x + -1x2 = 0 + 6x + -6x + x2 + -1x2
-4 + -6x + -1x2 = 6x + -6x + x2 + -1x2

Combine like terms: 6x + -6x = 0
-4 + -6x + -1x2 = 0 + x2 + -1x2
-4 + -6x + -1x2 = x2 + -1x2

Combine like terms: x2 + -1x2 = 0
-4 + -6x + -1x2 = 0

Factor out the Greatest Common Factor (GCF), '-1'.
-1(4 + 6x + x2) = 0

Ignore the factor -1.

Subproblem 1

Set the factor '(4 + 6x + x2)' equal to zero and attempt to solve: Simplifying 4 + 6x + x2 = 0 Solving 4 + 6x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-4' to each side of the equation. 4 + 6x + -4 + x2 = 0 + -4 Reorder the terms: 4 + -4 + 6x + x2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + 6x + x2 = 0 + -4 6x + x2 = 0 + -4 Combine like terms: 0 + -4 = -4 6x + x2 = -4 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 = -4 + 9 Reorder the terms: 9 + 6x + x2 = -4 + 9 Combine like terms: -4 + 9 = 5 9 + 6x + x2 = 5 Factor a perfect square on the left side: (x + 3)(x + 3) = 5 Calculate the square root of the right side: 2.236067978 Break this problem into two subproblems by setting (x + 3) equal to 2.236067978 and -2.236067978.

Subproblem 1

x + 3 = 2.236067978 Simplifying x + 3 = 2.236067978 Reorder the terms: 3 + x = 2.236067978 Solving 3 + x = 2.236067978 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = 2.236067978 + -3 Combine like terms: 3 + -3 = 0 0 + x = 2.236067978 + -3 x = 2.236067978 + -3 Combine like terms: 2.236067978 + -3 = -0.763932022 x = -0.763932022 Simplifying x = -0.763932022

Subproblem 2

x + 3 = -2.236067978 Simplifying x + 3 = -2.236067978 Reorder the terms: 3 + x = -2.236067978 Solving 3 + x = -2.236067978 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = -2.236067978 + -3 Combine like terms: 3 + -3 = 0 0 + x = -2.236067978 + -3 x = -2.236067978 + -3 Combine like terms: -2.236067978 + -3 = -5.236067978 x = -5.236067978 Simplifying x = -5.236067978
