Simplifying x2 + -1x + -12.01 = 0 Reorder the terms: -12.01 + -1x + x2 = 0 Solving -12.01 + -1x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '12.01' to each side of the equation. -12.01 + -1x + 12.01 + x2 = 0 + 12.01 Reorder the terms: -12.01 + 12.01 + -1x + x2 = 0 + 12.01 Combine like terms: -12.01 + 12.01 = 0.00 0.00 + -1x + x2 = 0 + 12.01 -1x + x2 = 0 + 12.01 Combine like terms: 0 + 12.01 = 12.01 -1x + x2 = 12.01 The x term is -1x. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1x + 0.25 + x2 = 12.01 + 0.25 Reorder the terms: 0.25 + -1x + x2 = 12.01 + 0.25 Combine like terms: 12.01 + 0.25 = 12.26 0.25 + -1x + x2 = 12.26 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = 12.26 Calculate the square root of the right side: 3.50142828 Break this problem into two subproblems by setting (x + -0.5) equal to 3.50142828 and -3.50142828.Subproblem 1
x + -0.5 = 3.50142828 Simplifying x + -0.5 = 3.50142828 Reorder the terms: -0.5 + x = 3.50142828 Solving -0.5 + x = 3.50142828 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = 3.50142828 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = 3.50142828 + 0.5 x = 3.50142828 + 0.5 Combine like terms: 3.50142828 + 0.5 = 4.00142828 x = 4.00142828 Simplifying x = 4.00142828Subproblem 2
x + -0.5 = -3.50142828 Simplifying x + -0.5 = -3.50142828 Reorder the terms: -0.5 + x = -3.50142828 Solving -0.5 + x = -3.50142828 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = -3.50142828 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = -3.50142828 + 0.5 x = -3.50142828 + 0.5 Combine like terms: -3.50142828 + 0.5 = -3.00142828 x = -3.00142828 Simplifying x = -3.00142828Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.00142828, -3.00142828}
