Simplifying -0.5x2 + 0.5x + 4.99 = 0 Reorder the terms: 4.99 + 0.5x + -0.5x2 = 0 Solving 4.99 + 0.5x + -0.5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -0.5 the coefficient of the squared term: Divide each side by '-0.5'. -9.98 + -1x + x2 = 0 Move the constant term to the right: Add '9.98' to each side of the equation. -9.98 + -1x + 9.98 + x2 = 0 + 9.98 Reorder the terms: -9.98 + 9.98 + -1x + x2 = 0 + 9.98 Combine like terms: -9.98 + 9.98 = 0.00 0.00 + -1x + x2 = 0 + 9.98 -1x + x2 = 0 + 9.98 Combine like terms: 0 + 9.98 = 9.98 -1x + x2 = 9.98 The x term is -1x. 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. -1x + 0.25 + x2 = 9.98 + 0.25 Reorder the terms: 0.25 + -1x + x2 = 9.98 + 0.25 Combine like terms: 9.98 + 0.25 = 10.23 0.25 + -1x + x2 = 10.23 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = 10.23 Calculate the square root of the right side: 3.198437118 Break this problem into two subproblems by setting (x + -0.5) equal to 3.198437118 and -3.198437118.Subproblem 1
x + -0.5 = 3.198437118 Simplifying x + -0.5 = 3.198437118 Reorder the terms: -0.5 + x = 3.198437118 Solving -0.5 + x = 3.198437118 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 = 3.198437118 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = 3.198437118 + 0.5 x = 3.198437118 + 0.5 Combine like terms: 3.198437118 + 0.5 = 3.698437118 x = 3.698437118 Simplifying x = 3.698437118Subproblem 2
x + -0.5 = -3.198437118 Simplifying x + -0.5 = -3.198437118 Reorder the terms: -0.5 + x = -3.198437118 Solving -0.5 + x = -3.198437118 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 = -3.198437118 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = -3.198437118 + 0.5 x = -3.198437118 + 0.5 Combine like terms: -3.198437118 + 0.5 = -2.698437118 x = -2.698437118 Simplifying x = -2.698437118Solution
