Simplifying 0.2x2 + -0.4x + -1 = 1 + -3x Reorder the terms: -1 + -0.4x + 0.2x2 = 1 + -3x Solving -1 + -0.4x + 0.2x2 = 1 + -3x Solving for variable 'x'. Reorder the terms: -1 + -1 + -0.4x + 3x + 0.2x2 = 1 + -3x + -1 + 3x Combine like terms: -1 + -1 = -2 -2 + -0.4x + 3x + 0.2x2 = 1 + -3x + -1 + 3x Combine like terms: -0.4x + 3x = 2.6x -2 + 2.6x + 0.2x2 = 1 + -3x + -1 + 3x Reorder the terms: -2 + 2.6x + 0.2x2 = 1 + -1 + -3x + 3x Combine like terms: 1 + -1 = 0 -2 + 2.6x + 0.2x2 = 0 + -3x + 3x -2 + 2.6x + 0.2x2 = -3x + 3x Combine like terms: -3x + 3x = 0 -2 + 2.6x + 0.2x2 = 0 Begin completing the square. Divide all terms by 0.2 the coefficient of the squared term: Divide each side by '0.2'. -10 + 13x + x2 = 0 Move the constant term to the right: Add '10' to each side of the equation. -10 + 13x + 10 + x2 = 0 + 10 Reorder the terms: -10 + 10 + 13x + x2 = 0 + 10 Combine like terms: -10 + 10 = 0 0 + 13x + x2 = 0 + 10 13x + x2 = 0 + 10 Combine like terms: 0 + 10 = 10 13x + x2 = 10 The x term is 13x. Take half its coefficient (6.5). Square it (42.25) and add it to both sides. Add '42.25' to each side of the equation. 13x + 42.25 + x2 = 10 + 42.25 Reorder the terms: 42.25 + 13x + x2 = 10 + 42.25 Combine like terms: 10 + 42.25 = 52.25 42.25 + 13x + x2 = 52.25 Factor a perfect square on the left side: (x + 6.5)(x + 6.5) = 52.25 Calculate the square root of the right side: 7.228416147 Break this problem into two subproblems by setting (x + 6.5) equal to 7.228416147 and -7.228416147.Subproblem 1
x + 6.5 = 7.228416147 Simplifying x + 6.5 = 7.228416147 Reorder the terms: 6.5 + x = 7.228416147 Solving 6.5 + x = 7.228416147 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6.5' to each side of the equation. 6.5 + -6.5 + x = 7.228416147 + -6.5 Combine like terms: 6.5 + -6.5 = 0.0 0.0 + x = 7.228416147 + -6.5 x = 7.228416147 + -6.5 Combine like terms: 7.228416147 + -6.5 = 0.728416147 x = 0.728416147 Simplifying x = 0.728416147Subproblem 2
x + 6.5 = -7.228416147 Simplifying x + 6.5 = -7.228416147 Reorder the terms: 6.5 + x = -7.228416147 Solving 6.5 + x = -7.228416147 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6.5' to each side of the equation. 6.5 + -6.5 + x = -7.228416147 + -6.5 Combine like terms: 6.5 + -6.5 = 0.0 0.0 + x = -7.228416147 + -6.5 x = -7.228416147 + -6.5 Combine like terms: -7.228416147 + -6.5 = -13.728416147 x = -13.728416147 Simplifying x = -13.728416147Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.728416147, -13.728416147}
