Simplifying (x) = x2 + -14x + 45 x = x2 + -14x + 45 Reorder the terms: x = 45 + -14x + x2 Solving x = 45 + -14x + x2 Solving for variable 'x'. Reorder the terms: -45 + x + 14x + -1x2 = 45 + -14x + x2 + -45 + 14x + -1x2 Combine like terms: x + 14x = 15x -45 + 15x + -1x2 = 45 + -14x + x2 + -45 + 14x + -1x2 Reorder the terms: -45 + 15x + -1x2 = 45 + -45 + -14x + 14x + x2 + -1x2 Combine like terms: 45 + -45 = 0 -45 + 15x + -1x2 = 0 + -14x + 14x + x2 + -1x2 -45 + 15x + -1x2 = -14x + 14x + x2 + -1x2 Combine like terms: -14x + 14x = 0 -45 + 15x + -1x2 = 0 + x2 + -1x2 -45 + 15x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -45 + 15x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 45 + -15x + x2 = 0 Move the constant term to the right: Add '-45' to each side of the equation. 45 + -15x + -45 + x2 = 0 + -45 Reorder the terms: 45 + -45 + -15x + x2 = 0 + -45 Combine like terms: 45 + -45 = 0 0 + -15x + x2 = 0 + -45 -15x + x2 = 0 + -45 Combine like terms: 0 + -45 = -45 -15x + x2 = -45 The x term is -15x. Take half its coefficient (-7.5). Square it (56.25) and add it to both sides. Add '56.25' to each side of the equation. -15x + 56.25 + x2 = -45 + 56.25 Reorder the terms: 56.25 + -15x + x2 = -45 + 56.25 Combine like terms: -45 + 56.25 = 11.25 56.25 + -15x + x2 = 11.25 Factor a perfect square on the left side: (x + -7.5)(x + -7.5) = 11.25 Calculate the square root of the right side: 3.354101966 Break this problem into two subproblems by setting (x + -7.5) equal to 3.354101966 and -3.354101966.Subproblem 1
x + -7.5 = 3.354101966 Simplifying x + -7.5 = 3.354101966 Reorder the terms: -7.5 + x = 3.354101966 Solving -7.5 + x = 3.354101966 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '7.5' to each side of the equation. -7.5 + 7.5 + x = 3.354101966 + 7.5 Combine like terms: -7.5 + 7.5 = 0.0 0.0 + x = 3.354101966 + 7.5 x = 3.354101966 + 7.5 Combine like terms: 3.354101966 + 7.5 = 10.854101966 x = 10.854101966 Simplifying x = 10.854101966Subproblem 2
x + -7.5 = -3.354101966 Simplifying x + -7.5 = -3.354101966 Reorder the terms: -7.5 + x = -3.354101966 Solving -7.5 + x = -3.354101966 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '7.5' to each side of the equation. -7.5 + 7.5 + x = -3.354101966 + 7.5 Combine like terms: -7.5 + 7.5 = 0.0 0.0 + x = -3.354101966 + 7.5 x = -3.354101966 + 7.5 Combine like terms: -3.354101966 + 7.5 = 4.145898034 x = 4.145898034 Simplifying x = 4.145898034Solution
The solution to the problem is based on the solutions from the subproblems. x = {10.854101966, 4.145898034}
