Simplifying x2 + 3x + 27 = 180 Reorder the terms: 27 + 3x + x2 = 180 Solving 27 + 3x + x2 = 180 Solving for variable 'x'. Reorder the terms: 27 + -180 + 3x + x2 = 180 + -180 Combine like terms: 27 + -180 = -153 -153 + 3x + x2 = 180 + -180 Combine like terms: 180 + -180 = 0 -153 + 3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '153' to each side of the equation. -153 + 3x + 153 + x2 = 0 + 153 Reorder the terms: -153 + 153 + 3x + x2 = 0 + 153 Combine like terms: -153 + 153 = 0 0 + 3x + x2 = 0 + 153 3x + x2 = 0 + 153 Combine like terms: 0 + 153 = 153 3x + x2 = 153 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 = 153 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 153 + 2.25 Combine like terms: 153 + 2.25 = 155.25 2.25 + 3x + x2 = 155.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 155.25 Calculate the square root of the right side: 12.459935794 Break this problem into two subproblems by setting (x + 1.5) equal to 12.459935794 and -12.459935794.Subproblem 1
x + 1.5 = 12.459935794 Simplifying x + 1.5 = 12.459935794 Reorder the terms: 1.5 + x = 12.459935794 Solving 1.5 + x = 12.459935794 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 = 12.459935794 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 12.459935794 + -1.5 x = 12.459935794 + -1.5 Combine like terms: 12.459935794 + -1.5 = 10.959935794 x = 10.959935794 Simplifying x = 10.959935794Subproblem 2
x + 1.5 = -12.459935794 Simplifying x + 1.5 = -12.459935794 Reorder the terms: 1.5 + x = -12.459935794 Solving 1.5 + x = -12.459935794 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 = -12.459935794 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -12.459935794 + -1.5 x = -12.459935794 + -1.5 Combine like terms: -12.459935794 + -1.5 = -13.959935794 x = -13.959935794 Simplifying x = -13.959935794Solution
The solution to the problem is based on the solutions from the subproblems. x = {10.959935794, -13.959935794}
