Subproblem 1

Set the factor '(1 + -5x + x2)' equal to zero and attempt to solve: Simplifying 1 + -5x + x2 = 0 Solving 1 + -5x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-1' to each side of the equation. 1 + -5x + -1 + x2 = 0 + -1 Reorder the terms: 1 + -1 + -5x + x2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -5x + x2 = 0 + -1 -5x + x2 = 0 + -1 Combine like terms: 0 + -1 = -1 -5x + x2 = -1 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = -1 + 6.25 Reorder the terms: 6.25 + -5x + x2 = -1 + 6.25 Combine like terms: -1 + 6.25 = 5.25 6.25 + -5x + x2 = 5.25 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = 5.25 Calculate the square root of the right side: 2.291287847 Break this problem into two subproblems by setting (x + -2.5) equal to 2.291287847 and -2.291287847.
