Simplifying x2 + 29x + 30 = 0 Reorder the terms: 30 + 29x + x2 = 0 Solving 30 + 29x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-30' to each side of the equation. 30 + 29x + -30 + x2 = 0 + -30 Reorder the terms: 30 + -30 + 29x + x2 = 0 + -30 Combine like terms: 30 + -30 = 0 0 + 29x + x2 = 0 + -30 29x + x2 = 0 + -30 Combine like terms: 0 + -30 = -30 29x + x2 = -30 The x term is 29x. Take half its coefficient (14.5). Square it (210.25) and add it to both sides. Add '210.25' to each side of the equation. 29x + 210.25 + x2 = -30 + 210.25 Reorder the terms: 210.25 + 29x + x2 = -30 + 210.25 Combine like terms: -30 + 210.25 = 180.25 210.25 + 29x + x2 = 180.25 Factor a perfect square on the left side: (x + 14.5)(x + 14.5) = 180.25 Calculate the square root of the right side: 13.425721582 Break this problem into two subproblems by setting (x + 14.5) equal to 13.425721582 and -13.425721582.Subproblem 1
x + 14.5 = 13.425721582 Simplifying x + 14.5 = 13.425721582 Reorder the terms: 14.5 + x = 13.425721582 Solving 14.5 + x = 13.425721582 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-14.5' to each side of the equation. 14.5 + -14.5 + x = 13.425721582 + -14.5 Combine like terms: 14.5 + -14.5 = 0.0 0.0 + x = 13.425721582 + -14.5 x = 13.425721582 + -14.5 Combine like terms: 13.425721582 + -14.5 = -1.074278418 x = -1.074278418 Simplifying x = -1.074278418Subproblem 2
x + 14.5 = -13.425721582 Simplifying x + 14.5 = -13.425721582 Reorder the terms: 14.5 + x = -13.425721582 Solving 14.5 + x = -13.425721582 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-14.5' to each side of the equation. 14.5 + -14.5 + x = -13.425721582 + -14.5 Combine like terms: 14.5 + -14.5 = 0.0 0.0 + x = -13.425721582 + -14.5 x = -13.425721582 + -14.5 Combine like terms: -13.425721582 + -14.5 = -27.925721582 x = -27.925721582 Simplifying x = -27.925721582Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.074278418, -27.925721582}
