Simplifying x2 + -3x + -242 = 0 Reorder the terms: -242 + -3x + x2 = 0 Solving -242 + -3x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '242' to each side of the equation. -242 + -3x + 242 + x2 = 0 + 242 Reorder the terms: -242 + 242 + -3x + x2 = 0 + 242 Combine like terms: -242 + 242 = 0 0 + -3x + x2 = 0 + 242 -3x + x2 = 0 + 242 Combine like terms: 0 + 242 = 242 -3x + x2 = 242 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 = 242 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 242 + 2.25 Combine like terms: 242 + 2.25 = 244.25 2.25 + -3x + x2 = 244.25 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 244.25 Calculate the square root of the right side: 15.628499608 Break this problem into two subproblems by setting (x + -1.5) equal to 15.628499608 and -15.628499608.Subproblem 1
x + -1.5 = 15.628499608 Simplifying x + -1.5 = 15.628499608 Reorder the terms: -1.5 + x = 15.628499608 Solving -1.5 + x = 15.628499608 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 = 15.628499608 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 15.628499608 + 1.5 x = 15.628499608 + 1.5 Combine like terms: 15.628499608 + 1.5 = 17.128499608 x = 17.128499608 Simplifying x = 17.128499608Subproblem 2
x + -1.5 = -15.628499608 Simplifying x + -1.5 = -15.628499608 Reorder the terms: -1.5 + x = -15.628499608 Solving -1.5 + x = -15.628499608 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 = -15.628499608 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -15.628499608 + 1.5 x = -15.628499608 + 1.5 Combine like terms: -15.628499608 + 1.5 = -14.128499608 x = -14.128499608 Simplifying x = -14.128499608Solution
