Simplifying x2 + 25x + 16 = 0 Reorder the terms: 16 + 25x + x2 = 0 Solving 16 + 25x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-16' to each side of the equation. 16 + 25x + -16 + x2 = 0 + -16 Reorder the terms: 16 + -16 + 25x + x2 = 0 + -16 Combine like terms: 16 + -16 = 0 0 + 25x + x2 = 0 + -16 25x + x2 = 0 + -16 Combine like terms: 0 + -16 = -16 25x + x2 = -16 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 = -16 + 156.25 Reorder the terms: 156.25 + 25x + x2 = -16 + 156.25 Combine like terms: -16 + 156.25 = 140.25 156.25 + 25x + x2 = 140.25 Factor a perfect square on the left side: (x + 12.5)(x + 12.5) = 140.25 Calculate the square root of the right side: 11.842719282 Break this problem into two subproblems by setting (x + 12.5) equal to 11.842719282 and -11.842719282.Subproblem 1
x + 12.5 = 11.842719282 Simplifying x + 12.5 = 11.842719282 Reorder the terms: 12.5 + x = 11.842719282 Solving 12.5 + x = 11.842719282 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 = 11.842719282 + -12.5 Combine like terms: 12.5 + -12.5 = 0.0 0.0 + x = 11.842719282 + -12.5 x = 11.842719282 + -12.5 Combine like terms: 11.842719282 + -12.5 = -0.657280718 x = -0.657280718 Simplifying x = -0.657280718Subproblem 2
x + 12.5 = -11.842719282 Simplifying x + 12.5 = -11.842719282 Reorder the terms: 12.5 + x = -11.842719282 Solving 12.5 + x = -11.842719282 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 = -11.842719282 + -12.5 Combine like terms: 12.5 + -12.5 = 0.0 0.0 + x = -11.842719282 + -12.5 x = -11.842719282 + -12.5 Combine like terms: -11.842719282 + -12.5 = -24.342719282 x = -24.342719282 Simplifying x = -24.342719282Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.657280718, -24.342719282}
