Simplifying x2 + x + -59.2 = 0 Reorder the terms: -59.2 + x + x2 = 0 Solving -59.2 + x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '59.2' to each side of the equation. -59.2 + x + 59.2 + x2 = 0 + 59.2 Reorder the terms: -59.2 + 59.2 + x + x2 = 0 + 59.2 Combine like terms: -59.2 + 59.2 = 0.0 0.0 + x + x2 = 0 + 59.2 x + x2 = 0 + 59.2 Combine like terms: 0 + 59.2 = 59.2 x + x2 = 59.2 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. x + 0.25 + x2 = 59.2 + 0.25 Reorder the terms: 0.25 + x + x2 = 59.2 + 0.25 Combine like terms: 59.2 + 0.25 = 59.45 0.25 + x + x2 = 59.45 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 59.45 Calculate the square root of the right side: 7.71038261 Break this problem into two subproblems by setting (x + 0.5) equal to 7.71038261 and -7.71038261.Subproblem 1
x + 0.5 = 7.71038261 Simplifying x + 0.5 = 7.71038261 Reorder the terms: 0.5 + x = 7.71038261 Solving 0.5 + x = 7.71038261 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 7.71038261 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 7.71038261 + -0.5 x = 7.71038261 + -0.5 Combine like terms: 7.71038261 + -0.5 = 7.21038261 x = 7.21038261 Simplifying x = 7.21038261Subproblem 2
x + 0.5 = -7.71038261 Simplifying x + 0.5 = -7.71038261 Reorder the terms: 0.5 + x = -7.71038261 Solving 0.5 + x = -7.71038261 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = -7.71038261 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -7.71038261 + -0.5 x = -7.71038261 + -0.5 Combine like terms: -7.71038261 + -0.5 = -8.21038261 x = -8.21038261 Simplifying x = -8.21038261Solution
The solution to the problem is based on the solutions from the subproblems. x = {7.21038261, -8.21038261}
