Simplifying -1x(-2x + -4) = 5 Reorder the terms: -1x(-4 + -2x) = 5 (-4 * -1x + -2x * -1x) = 5 (4x + 2x2) = 5 Solving 4x + 2x2 = 5 Solving for variable 'x'. Reorder the terms: -5 + 4x + 2x2 = 5 + -5 Combine like terms: 5 + -5 = 0 -5 + 4x + 2x2 = 0 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 = 0.870828693 x = 0.870828693 Simplifying x = 0.870828693Subproblem 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 = -2.870828693 x = -2.870828693 Simplifying x = -2.870828693Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.870828693, -2.870828693}
