Simplifying 2x2 + 5x + -0.33 = 0 Reorder the terms: -0.33 + 5x + 2x2 = 0 Solving -0.33 + 5x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -0.165 + 2.5x + x2 = 0 Move the constant term to the right: Add '0.165' to each side of the equation. -0.165 + 2.5x + 0.165 + x2 = 0 + 0.165 Reorder the terms: -0.165 + 0.165 + 2.5x + x2 = 0 + 0.165 Combine like terms: -0.165 + 0.165 = 0.000 0.000 + 2.5x + x2 = 0 + 0.165 2.5x + x2 = 0 + 0.165 Combine like terms: 0 + 0.165 = 0.165 2.5x + x2 = 0.165 The x term is 2.5x. Take half its coefficient (1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. 2.5x + 1.5625 + x2 = 0.165 + 1.5625 Reorder the terms: 1.5625 + 2.5x + x2 = 0.165 + 1.5625 Combine like terms: 0.165 + 1.5625 = 1.7275 1.5625 + 2.5x + x2 = 1.7275 Factor a perfect square on the left side: (x + 1.25)(x + 1.25) = 1.7275 Calculate the square root of the right side: 1.314343943 Break this problem into two subproblems by setting (x + 1.25) equal to 1.314343943 and -1.314343943.Subproblem 1
x + 1.25 = 1.314343943 Simplifying x + 1.25 = 1.314343943 Reorder the terms: 1.25 + x = 1.314343943 Solving 1.25 + x = 1.314343943 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + x = 1.314343943 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = 1.314343943 + -1.25 x = 1.314343943 + -1.25 Combine like terms: 1.314343943 + -1.25 = 0.064343943 x = 0.064343943 Simplifying x = 0.064343943Subproblem 2
x + 1.25 = -1.314343943 Simplifying x + 1.25 = -1.314343943 Reorder the terms: 1.25 + x = -1.314343943 Solving 1.25 + x = -1.314343943 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + x = -1.314343943 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = -1.314343943 + -1.25 x = -1.314343943 + -1.25 Combine like terms: -1.314343943 + -1.25 = -2.564343943 x = -2.564343943 Simplifying x = -2.564343943Solution
