Simplifying x2 + 25x + 1 = 25 Reorder the terms: 1 + 25x + x2 = 25 Solving 1 + 25x + x2 = 25 Solving for variable 'x'. Reorder the terms: 1 + -25 + 25x + x2 = 25 + -25 Combine like terms: 1 + -25 = -24 -24 + 25x + x2 = 25 + -25 Combine like terms: 25 + -25 = 0 -24 + 25x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '24' to each side of the equation. -24 + 25x + 24 + x2 = 0 + 24 Reorder the terms: -24 + 24 + 25x + x2 = 0 + 24 Combine like terms: -24 + 24 = 0 0 + 25x + x2 = 0 + 24 25x + x2 = 0 + 24 Combine like terms: 0 + 24 = 24 25x + x2 = 24 The x term is 25x. Take half its coefficient (12.5). Square it (156.25) and add it to both sides. Add '156.25' to each side of the equation. 25x + 156.25 + x2 = 24 + 156.25 Reorder the terms: 156.25 + 25x + x2 = 24 + 156.25 Combine like terms: 24 + 156.25 = 180.25 156.25 + 25x + x2 = 180.25 Factor a perfect square on the left side: (x + 12.5)(x + 12.5) = 180.25 Calculate the square root of the right side: 13.425721582 Break this problem into two subproblems by setting (x + 12.5) equal to 13.425721582 and -13.425721582.Subproblem 1
x + 12.5 = 13.425721582 Simplifying x + 12.5 = 13.425721582 Reorder the terms: 12.5 + x = 13.425721582 Solving 12.5 + x = 13.425721582 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-12.5' to each side of the equation. 12.5 + -12.5 + x = 13.425721582 + -12.5 Combine like terms: 12.5 + -12.5 = 0.0 0.0 + x = 13.425721582 + -12.5 x = 13.425721582 + -12.5 Combine like terms: 13.425721582 + -12.5 = 0.925721582 x = 0.925721582 Simplifying x = 0.925721582Subproblem 2
x + 12.5 = -13.425721582 Simplifying x + 12.5 = -13.425721582 Reorder the terms: 12.5 + x = -13.425721582 Solving 12.5 + x = -13.425721582 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-12.5' to each side of the equation. 12.5 + -12.5 + x = -13.425721582 + -12.5 Combine like terms: 12.5 + -12.5 = 0.0 0.0 + x = -13.425721582 + -12.5 x = -13.425721582 + -12.5 Combine like terms: -13.425721582 + -12.5 = -25.925721582 x = -25.925721582 Simplifying x = -25.925721582Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.925721582, -25.925721582}
