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 Break this problem into two subproblems by setting (x + 3) equal to 2.449489743 and -2.449489743.

Subproblem 1

x + 3 = 2.449489743 Simplifying x + 3 = 2.449489743 Reorder the terms: 3 + x = 2.449489743 Solving 3 + x = 2.449489743 Solving for variable 'x'.
