Simplifying (2x * 2x) + 4x + -5 = 0 Reorder the terms for easier multiplication: (2 * 2x * x) + 4x + -5 = 0 Multiply 2 * 2 (4x * x) + 4x + -5 = 0 Multiply x * x (4x2) + 4x + -5 = 0 Reorder the terms: -5 + 4x + (4x2) = 0 Solving -5 + 4x + (4x2) = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -1.25 + x + x2 = 0 Move the constant term to the right: Add '1.25' to each side of the equation. -1.25 + x + 1.25 + x2 = 0 + 1.25 Reorder the terms: -1.25 + 1.25 + x + x2 = 0 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + x + x2 = 0 + 1.25 x + x2 = 0 + 1.25 Combine like terms: 0 + 1.25 = 1.25 x + x2 = 1.25 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. + 0.25 + x2 = 1.25 + 0.25 Combine like terms: + 0.25 = 1.25 1.25 + x2 = 1.25 + 0.25 Combine like terms: 1.25 + 0.25 = 1.5 1.25 + x2 = 1.5 Factor a perfect square on the left side: ((x) + 0.5)((x) + 0.5) = 1.5 Calculate the square root of the right side: 1.224744871 Break this problem into two subproblems by setting ((x) + 0.5) equal to 1.224744871 and -1.224744871.Subproblem 1
(x) + 0.5 = 1.224744871 Simplifying (x) + 0.5 = 1.224744871 x + 0.5 = 1.224744871 Reorder the terms: 0.5 + x = 1.224744871 Solving 0.5 + x = 1.224744871 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 1.224744871 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 1.224744871 + -0.5 x = 1.224744871 + -0.5 Combine like terms: 1.224744871 + -0.5 = 0.724744871 x = 0.724744871 Simplifying x = 0.724744871Subproblem 2
(x) + 0.5 = -1.224744871 Simplifying (x) + 0.5 = -1.224744871 x + 0.5 = -1.224744871 Reorder the terms: 0.5 + x = -1.224744871 Solving 0.5 + x = -1.224744871 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = -1.224744871 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -1.224744871 + -0.5 x = -1.224744871 + -0.5 Combine like terms: -1.224744871 + -0.5 = -1.724744871 x = -1.724744871 Simplifying x = -1.724744871Solution
