Subproblem 1

Set the factor '(-230 + x + x2)' equal to zero and attempt to solve: Simplifying -230 + x + x2 = 0 Solving -230 + x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '230' to each side of the equation. -230 + x + 230 + x2 = 0 + 230 Reorder the terms: -230 + 230 + x + x2 = 0 + 230 Combine like terms: -230 + 230 = 0 0 + x + x2 = 0 + 230 x + x2 = 0 + 230 Combine like terms: 0 + 230 = 230 x + x2 = 230 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. x + 0.25 + x2 = 230 + 0.25 Reorder the terms: 0.25 + x + x2 = 230 + 0.25 Combine like terms: 230 + 0.25 = 230.25 0.25 + x + x2 = 230.25 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 230.25 Calculate the square root of the right side: 15.173990905 Break this problem into two subproblems by setting (x + 0.5) equal to 15.173990905 and -15.173990905.

Subproblem 1

x + 0.5 = 15.173990905 Simplifying x + 0.5 = 15.173990905 Reorder the terms: 0.5 + x = 15.173990905 Solving 0.5 + x = 15.173990905 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 15.173990905 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 15.173990905 + -0.5 x = 15.173990905 + -0.5 Combine like terms: 15.173990905 + -0.5 = 14.673990905 x = 14.673990905 Simplifying x = 14.673990905

Subproblem 2

x + 0.5 = -15.173990905 Simplifying x + 0.5 = -15.173990905 Reorder the terms: 0.5 + x = -15.173990905 Solving 0.5 + x = -15.173990905 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = -15.173990905 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -15.173990905 + -0.5 x = -15.173990905 + -0.5 Combine like terms: -15.173990905 + -0.5 = -15.673990905 x = -15.673990905 Simplifying x = -15.673990905
