Simplifying x2 + 3x + -166 = 0 Reorder the terms: -166 + 3x + x2 = 0 Solving -166 + 3x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '166' to each side of the equation. -166 + 3x + 166 + x2 = 0 + 166 Reorder the terms: -166 + 166 + 3x + x2 = 0 + 166 Combine like terms: -166 + 166 = 0 0 + 3x + x2 = 0 + 166 3x + x2 = 0 + 166 Combine like terms: 0 + 166 = 166 3x + x2 = 166 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = 166 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 166 + 2.25 Combine like terms: 166 + 2.25 = 168.25 2.25 + 3x + x2 = 168.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 168.25 Calculate the square root of the right side: 12.971121771 Break this problem into two subproblems by setting (x + 1.5) equal to 12.971121771 and -12.971121771.Subproblem 1
x + 1.5 = 12.971121771 Simplifying x + 1.5 = 12.971121771 Reorder the terms: 1.5 + x = 12.971121771 Solving 1.5 + x = 12.971121771 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = 12.971121771 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 12.971121771 + -1.5 x = 12.971121771 + -1.5 Combine like terms: 12.971121771 + -1.5 = 11.471121771 x = 11.471121771 Simplifying x = 11.471121771Subproblem 2
x + 1.5 = -12.971121771 Simplifying x + 1.5 = -12.971121771 Reorder the terms: 1.5 + x = -12.971121771 Solving 1.5 + x = -12.971121771 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = -12.971121771 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -12.971121771 + -1.5 x = -12.971121771 + -1.5 Combine like terms: -12.971121771 + -1.5 = -14.471121771 x = -14.471121771 Simplifying x = -14.471121771Solution
The solution to the problem is based on the solutions from the subproblems. x = {11.471121771, -14.471121771}
