Simplifying x2 + -2.6x + -3.12 = 0 Reorder the terms: -3.12 + -2.6x + x2 = 0 Solving -3.12 + -2.6x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '3.12' to each side of the equation. -3.12 + -2.6x + 3.12 + x2 = 0 + 3.12 Reorder the terms: -3.12 + 3.12 + -2.6x + x2 = 0 + 3.12 Combine like terms: -3.12 + 3.12 = 0.00 0.00 + -2.6x + x2 = 0 + 3.12 -2.6x + x2 = 0 + 3.12 Combine like terms: 0 + 3.12 = 3.12 -2.6x + x2 = 3.12 The x term is -2.6x. Take half its coefficient (-1.3). Square it (1.69) and add it to both sides. Add '1.69' to each side of the equation. -2.6x + 1.69 + x2 = 3.12 + 1.69 Reorder the terms: 1.69 + -2.6x + x2 = 3.12 + 1.69 Combine like terms: 3.12 + 1.69 = 4.81 1.69 + -2.6x + x2 = 4.81 Factor a perfect square on the left side: (x + -1.3)(x + -1.3) = 4.81 Calculate the square root of the right side: 2.19317122 Break this problem into two subproblems by setting (x + -1.3) equal to 2.19317122 and -2.19317122.Subproblem 1
x + -1.3 = 2.19317122 Simplifying x + -1.3 = 2.19317122 Reorder the terms: -1.3 + x = 2.19317122 Solving -1.3 + x = 2.19317122 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.3' to each side of the equation. -1.3 + 1.3 + x = 2.19317122 + 1.3 Combine like terms: -1.3 + 1.3 = 0.0 0.0 + x = 2.19317122 + 1.3 x = 2.19317122 + 1.3 Combine like terms: 2.19317122 + 1.3 = 3.49317122 x = 3.49317122 Simplifying x = 3.49317122Subproblem 2
x + -1.3 = -2.19317122 Simplifying x + -1.3 = -2.19317122 Reorder the terms: -1.3 + x = -2.19317122 Solving -1.3 + x = -2.19317122 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.3' to each side of the equation. -1.3 + 1.3 + x = -2.19317122 + 1.3 Combine like terms: -1.3 + 1.3 = 0.0 0.0 + x = -2.19317122 + 1.3 x = -2.19317122 + 1.3 Combine like terms: -2.19317122 + 1.3 = -0.89317122 x = -0.89317122 Simplifying x = -0.89317122Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.49317122, -0.89317122}
