Simplifying x2 + 3x + (0.25) = 0 x2 + 3x + 0.25 = 0 Reorder the terms: 0.25 + 3x + x2 = 0 Solving 0.25 + 3x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-0.25' to each side of the equation. 0.25 + 3x + -0.25 + x2 = 0 + -0.25 Reorder the terms: 0.25 + -0.25 + 3x + x2 = 0 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + 3x + x2 = 0 + -0.25 3x + x2 = 0 + -0.25 Combine like terms: 0 + -0.25 = -0.25 3x + x2 = -0.25 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 = -0.25 + 2.25 Reorder the terms: 2.25 + 3x + x2 = -0.25 + 2.25 Combine like terms: -0.25 + 2.25 = 2 2.25 + 3x + x2 = 2 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 2 Calculate the square root of the right side: 1.414213562 Break this problem into two subproblems by setting (x + 1.5) equal to 1.414213562 and -1.414213562.Subproblem 1
x + 1.5 = 1.414213562 Simplifying x + 1.5 = 1.414213562 Reorder the terms: 1.5 + x = 1.414213562 Solving 1.5 + x = 1.414213562 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 = 1.414213562 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 1.414213562 + -1.5 x = 1.414213562 + -1.5 Combine like terms: 1.414213562 + -1.5 = -0.085786438 x = -0.085786438 Simplifying x = -0.085786438Subproblem 2
x + 1.5 = -1.414213562 Simplifying x + 1.5 = -1.414213562 Reorder the terms: 1.5 + x = -1.414213562 Solving 1.5 + x = -1.414213562 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 = -1.414213562 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -1.414213562 + -1.5 x = -1.414213562 + -1.5 Combine like terms: -1.414213562 + -1.5 = -2.914213562 x = -2.914213562 Simplifying x = -2.914213562Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.085786438, -2.914213562}
