Simplifying x2 + 25x + -120 = 0 Reorder the terms: -120 + 25x + x2 = 0 Solving -120 + 25x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '120' to each side of the equation. -120 + 25x + 120 + x2 = 0 + 120 Reorder the terms: -120 + 120 + 25x + x2 = 0 + 120 Combine like terms: -120 + 120 = 0 0 + 25x + x2 = 0 + 120 25x + x2 = 0 + 120 Combine like terms: 0 + 120 = 120 25x + x2 = 120 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 = 120 + 156.25 Reorder the terms: 156.25 + 25x + x2 = 120 + 156.25 Combine like terms: 120 + 156.25 = 276.25 156.25 + 25x + x2 = 276.25 Factor a perfect square on the left side: (x + 12.5)(x + 12.5) = 276.25 Calculate the square root of the right side: 16.620770139 Break this problem into two subproblems by setting (x + 12.5) equal to 16.620770139 and -16.620770139.Subproblem 1
x + 12.5 = 16.620770139 Simplifying x + 12.5 = 16.620770139 Reorder the terms: 12.5 + x = 16.620770139 Solving 12.5 + x = 16.620770139 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 = 16.620770139 + -12.5 Combine like terms: 12.5 + -12.5 = 0.0 0.0 + x = 16.620770139 + -12.5 x = 16.620770139 + -12.5 Combine like terms: 16.620770139 + -12.5 = 4.120770139 x = 4.120770139 Simplifying x = 4.120770139Subproblem 2
x + 12.5 = -16.620770139 Simplifying x + 12.5 = -16.620770139 Reorder the terms: 12.5 + x = -16.620770139 Solving 12.5 + x = -16.620770139 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 = -16.620770139 + -12.5 Combine like terms: 12.5 + -12.5 = 0.0 0.0 + x = -16.620770139 + -12.5 x = -16.620770139 + -12.5 Combine like terms: -16.620770139 + -12.5 = -29.120770139 x = -29.120770139 Simplifying x = -29.120770139Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.120770139, -29.120770139}
