Simplifying 5x2 + -15x + 1 = 0 Reorder the terms: 1 + -15x + 5x2 = 0 Solving 1 + -15x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 0.2 + -3x + x2 = 0 Move the constant term to the right: Add '-0.2' to each side of the equation. 0.2 + -3x + -0.2 + x2 = 0 + -0.2 Reorder the terms: 0.2 + -0.2 + -3x + x2 = 0 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + -3x + x2 = 0 + -0.2 -3x + x2 = 0 + -0.2 Combine like terms: 0 + -0.2 = -0.2 -3x + x2 = -0.2 The x term is -3x. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3x + 2.25 + x2 = -0.2 + 2.25 Reorder the terms: 2.25 + -3x + x2 = -0.2 + 2.25 Combine like terms: -0.2 + 2.25 = 2.05 2.25 + -3x + x2 = 2.05 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 2.05 Calculate the square root of the right side: 1.431782106 Break this problem into two subproblems by setting (x + -1.5) equal to 1.431782106 and -1.431782106.Subproblem 1
x + -1.5 = 1.431782106 Simplifying x + -1.5 = 1.431782106 Reorder the terms: -1.5 + x = 1.431782106 Solving -1.5 + x = 1.431782106 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = 1.431782106 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 1.431782106 + 1.5 x = 1.431782106 + 1.5 Combine like terms: 1.431782106 + 1.5 = 2.931782106 x = 2.931782106 Simplifying x = 2.931782106Subproblem 2
x + -1.5 = -1.431782106 Simplifying x + -1.5 = -1.431782106 Reorder the terms: -1.5 + x = -1.431782106 Solving -1.5 + x = -1.431782106 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = -1.431782106 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -1.431782106 + 1.5 x = -1.431782106 + 1.5 Combine like terms: -1.431782106 + 1.5 = 0.068217894 x = 0.068217894 Simplifying x = 0.068217894Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.931782106, 0.068217894}
