Simplifying x2 + -2.2x + -4 = 0 Reorder the terms: -4 + -2.2x + x2 = 0 Solving -4 + -2.2x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '4' to each side of the equation. -4 + -2.2x + 4 + x2 = 0 + 4 Reorder the terms: -4 + 4 + -2.2x + x2 = 0 + 4 Combine like terms: -4 + 4 = 0 0 + -2.2x + x2 = 0 + 4 -2.2x + x2 = 0 + 4 Combine like terms: 0 + 4 = 4 -2.2x + x2 = 4 The x term is -2.2x. Take half its coefficient (-1.1). Square it (1.21) and add it to both sides. Add '1.21' to each side of the equation. -2.2x + 1.21 + x2 = 4 + 1.21 Reorder the terms: 1.21 + -2.2x + x2 = 4 + 1.21 Combine like terms: 4 + 1.21 = 5.21 1.21 + -2.2x + x2 = 5.21 Factor a perfect square on the left side: (x + -1.1)(x + -1.1) = 5.21 Calculate the square root of the right side: 2.282542442 Break this problem into two subproblems by setting (x + -1.1) equal to 2.282542442 and -2.282542442.Subproblem 1
x + -1.1 = 2.282542442 Simplifying x + -1.1 = 2.282542442 Reorder the terms: -1.1 + x = 2.282542442 Solving -1.1 + x = 2.282542442 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.1' to each side of the equation. -1.1 + 1.1 + x = 2.282542442 + 1.1 Combine like terms: -1.1 + 1.1 = 0.0 0.0 + x = 2.282542442 + 1.1 x = 2.282542442 + 1.1 Combine like terms: 2.282542442 + 1.1 = 3.382542442 x = 3.382542442 Simplifying x = 3.382542442Subproblem 2
x + -1.1 = -2.282542442 Simplifying x + -1.1 = -2.282542442 Reorder the terms: -1.1 + x = -2.282542442 Solving -1.1 + x = -2.282542442 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.1' to each side of the equation. -1.1 + 1.1 + x = -2.282542442 + 1.1 Combine like terms: -1.1 + 1.1 = 0.0 0.0 + x = -2.282542442 + 1.1 x = -2.282542442 + 1.1 Combine like terms: -2.282542442 + 1.1 = -1.182542442 x = -1.182542442 Simplifying x = -1.182542442Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.382542442, -1.182542442}
