Simplifying -1x2 + 13x + -13.3 = 0 Reorder the terms: -13.3 + 13x + -1x2 = 0 Solving -13.3 + 13x + -1x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 13.3 + -13x + x2 = 0 Move the constant term to the right: Add '-13.3' to each side of the equation. 13.3 + -13x + -13.3 + x2 = 0 + -13.3 Reorder the terms: 13.3 + -13.3 + -13x + x2 = 0 + -13.3 Combine like terms: 13.3 + -13.3 = 0.0 0.0 + -13x + x2 = 0 + -13.3 -13x + x2 = 0 + -13.3 Combine like terms: 0 + -13.3 = -13.3 -13x + x2 = -13.3 The x term is -13x. Take half its coefficient (-6.5). Square it (42.25) and add it to both sides. Add '42.25' to each side of the equation. -13x + 42.25 + x2 = -13.3 + 42.25 Reorder the terms: 42.25 + -13x + x2 = -13.3 + 42.25 Combine like terms: -13.3 + 42.25 = 28.95 42.25 + -13x + x2 = 28.95 Factor a perfect square on the left side: (x + -6.5)(x + -6.5) = 28.95 Calculate the square root of the right side: 5.380520421 Break this problem into two subproblems by setting (x + -6.5) equal to 5.380520421 and -5.380520421.Subproblem 1
