Simplifying -2x2 + -1x + 5 = 0 Reorder the terms: 5 + -1x + -2x2 = 0 Solving 5 + -1x + -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'. -2.5 + 0.5x + x2 = 0 Move the constant term to the right: Add '2.5' to each side of the equation. -2.5 + 0.5x + 2.5 + x2 = 0 + 2.5 Reorder the terms: -2.5 + 2.5 + 0.5x + x2 = 0 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + 0.5x + x2 = 0 + 2.5 0.5x + x2 = 0 + 2.5 Combine like terms: 0 + 2.5 = 2.5 0.5x + x2 = 2.5 The x term is 0.5x. Take half its coefficient (0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. 0.5x + 0.0625 + x2 = 2.5 + 0.0625 Reorder the terms: 0.0625 + 0.5x + x2 = 2.5 + 0.0625 Combine like terms: 2.5 + 0.0625 = 2.5625 0.0625 + 0.5x + x2 = 2.5625 Factor a perfect square on the left side: (x + 0.25)(x + 0.25) = 2.5625 Calculate the square root of the right side: 1.600781059 Break this problem into two subproblems by setting (x + 0.25) equal to 1.600781059 and -1.600781059.Subproblem 1
x + 0.25 = 1.600781059 Simplifying x + 0.25 = 1.600781059 Reorder the terms: 0.25 + x = 1.600781059 Solving 0.25 + x = 1.600781059 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.25' to each side of the equation. 0.25 + -0.25 + x = 1.600781059 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + x = 1.600781059 + -0.25 x = 1.600781059 + -0.25 Combine like terms: 1.600781059 + -0.25 = 1.350781059 x = 1.350781059 Simplifying x = 1.350781059Subproblem 2
x + 0.25 = -1.600781059 Simplifying x + 0.25 = -1.600781059 Reorder the terms: 0.25 + x = -1.600781059 Solving 0.25 + x = -1.600781059 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.25' to each side of the equation. 0.25 + -0.25 + x = -1.600781059 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + x = -1.600781059 + -0.25 x = -1.600781059 + -0.25 Combine like terms: -1.600781059 + -0.25 = -1.850781059 x = -1.850781059 Simplifying x = -1.850781059Solution
