Simplifying x2 + 3x + -63 = 0 Reorder the terms: -63 + 3x + x2 = 0 Solving -63 + 3x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '63' to each side of the equation. -63 + 3x + 63 + x2 = 0 + 63 Reorder the terms: -63 + 63 + 3x + x2 = 0 + 63 Combine like terms: -63 + 63 = 0 0 + 3x + x2 = 0 + 63 3x + x2 = 0 + 63 Combine like terms: 0 + 63 = 63 3x + x2 = 63 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 = 63 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 63 + 2.25 Combine like terms: 63 + 2.25 = 65.25 2.25 + 3x + x2 = 65.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 65.25 Calculate the square root of the right side: 8.077747211 Break this problem into two subproblems by setting (x + 1.5) equal to 8.077747211 and -8.077747211.Subproblem 1
x + 1.5 = 8.077747211 Simplifying x + 1.5 = 8.077747211 Reorder the terms: 1.5 + x = 8.077747211 Solving 1.5 + x = 8.077747211 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 = 8.077747211 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 8.077747211 + -1.5 x = 8.077747211 + -1.5 Combine like terms: 8.077747211 + -1.5 = 6.577747211 x = 6.577747211 Simplifying x = 6.577747211Subproblem 2
x + 1.5 = -8.077747211 Simplifying x + 1.5 = -8.077747211 Reorder the terms: 1.5 + x = -8.077747211 Solving 1.5 + x = -8.077747211 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 = -8.077747211 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -8.077747211 + -1.5 x = -8.077747211 + -1.5 Combine like terms: -8.077747211 + -1.5 = -9.577747211 x = -9.577747211 Simplifying x = -9.577747211Solution
