Subproblem 1

Set the factor '(-19 + -1x + x2)' equal to zero and attempt to solve: Simplifying -19 + -1x + x2 = 0 Solving -19 + -1x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '19' to each side of the equation. -19 + -1x + 19 + x2 = 0 + 19 Reorder the terms: -19 + 19 + -1x + x2 = 0 + 19 Combine like terms: -19 + 19 = 0 0 + -1x + x2 = 0 + 19 -1x + x2 = 0 + 19 Combine like terms: 0 + 19 = 19 -1x + x2 = 19 The x term is -1x. 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. -1x + 0.25 + x2 = 19 + 0.25 Reorder the terms: 0.25 + -1x + x2 = 19 + 0.25 Combine like terms: 19 + 0.25 = 19.25 0.25 + -1x + x2 = 19.25 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = 19.25 Calculate the square root of the right side: 4.387482194 Break this problem into two subproblems by setting (x + -0.5) equal to 4.387482194 and -4.387482194.

Subproblem 1

x + -0.5 = 4.387482194 Simplifying x + -0.5 = 4.387482194 Reorder the terms: -0.5 + x = 4.387482194 Solving -0.5 + x = 4.387482194 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 = 4.387482194 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = 4.387482194 + 0.5 x = 4.387482194 + 0.5 Combine like terms: 4.387482194 + 0.5 = 4.887482194 x = 4.887482194 Simplifying x = 4.887482194

Subproblem 2

x + -0.5 = -4.387482194 Simplifying x + -0.5 = -4.387482194 Reorder the terms: -0.5 + x = -4.387482194 Solving -0.5 + x = -4.387482194 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 = -4.387482194 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = -4.387482194 + 0.5 x = -4.387482194 + 0.5 Combine like terms: -4.387482194 + 0.5 = -3.887482194 x = -3.887482194 Simplifying x = -3.887482194
