Simplifying 2x2 + -4x + -5 = 0 Reorder the terms: -5 + -4x + 2x2 = 0 Solving -5 + -4x + 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 + -2x + x2 = 0 Move the constant term to the right: Add '2.5' to each side of the equation. -2.5 + -2x + 2.5 + x2 = 0 + 2.5 Reorder the terms: -2.5 + 2.5 + -2x + x2 = 0 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + -2x + x2 = 0 + 2.5 -2x + x2 = 0 + 2.5 Combine like terms: 0 + 2.5 = 2.5 -2x + x2 = 2.5 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = 2.5 + 1 Reorder the terms: 1 + -2x + x2 = 2.5 + 1 Combine like terms: 2.5 + 1 = 3.5 1 + -2x + x2 = 3.5 Factor a perfect square on the left side: (x + -1)(x + -1) = 3.5 Calculate the square root of the right side: 1.870828693 Break this problem into two subproblems by setting (x + -1) equal to 1.870828693 and -1.870828693.Subproblem 1
x + -1 = 1.870828693 Simplifying x + -1 = 1.870828693 Reorder the terms: -1 + x = 1.870828693 Solving -1 + x = 1.870828693 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = 1.870828693 + 1 Combine like terms: -1 + 1 = 0 0 + x = 1.870828693 + 1 x = 1.870828693 + 1 Combine like terms: 1.870828693 + 1 = 2.870828693 x = 2.870828693 Simplifying x = 2.870828693Subproblem 2
x + -1 = -1.870828693 Simplifying x + -1 = -1.870828693 Reorder the terms: -1 + x = -1.870828693 Solving -1 + x = -1.870828693 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = -1.870828693 + 1 Combine like terms: -1 + 1 = 0 0 + x = -1.870828693 + 1 x = -1.870828693 + 1 Combine like terms: -1.870828693 + 1 = -0.870828693 x = -0.870828693 Simplifying x = -0.870828693Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.870828693, -0.870828693}
