Simplifying x(x + 5) = 287 Reorder the terms: x(5 + x) = 287 (5 * x + x * x) = 287 (5x + x2) = 287 Solving 5x + x2 = 287 Solving for variable 'x'. Reorder the terms: -287 + 5x + x2 = 287 + -287 Combine like terms: 287 + -287 = 0 -287 + 5x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '287' to each side of the equation. -287 + 5x + 287 + x2 = 0 + 287 Reorder the terms: -287 + 287 + 5x + x2 = 0 + 287 Combine like terms: -287 + 287 = 0 0 + 5x + x2 = 0 + 287 5x + x2 = 0 + 287 Combine like terms: 0 + 287 = 287 5x + x2 = 287 The x term is 5x. Take half its coefficient (2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. 5x + 6.25 + x2 = 287 + 6.25 Reorder the terms: 6.25 + 5x + x2 = 287 + 6.25 Combine like terms: 287 + 6.25 = 293.25 6.25 + 5x + x2 = 293.25 Factor a perfect square on the left side: (x + 2.5)(x + 2.5) = 293.25 Calculate the square root of the right side: 17.12454379 Break this problem into two subproblems by setting (x + 2.5) equal to 17.12454379 and -17.12454379.Subproblem 1
x + 2.5 = 17.12454379 Simplifying x + 2.5 = 17.12454379 Reorder the terms: 2.5 + x = 17.12454379 Solving 2.5 + x = 17.12454379 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + x = 17.12454379 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = 17.12454379 + -2.5 x = 17.12454379 + -2.5 Combine like terms: 17.12454379 + -2.5 = 14.62454379 x = 14.62454379 Simplifying x = 14.62454379Subproblem 2
x + 2.5 = -17.12454379 Simplifying x + 2.5 = -17.12454379 Reorder the terms: 2.5 + x = -17.12454379 Solving 2.5 + x = -17.12454379 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + x = -17.12454379 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = -17.12454379 + -2.5 x = -17.12454379 + -2.5 Combine like terms: -17.12454379 + -2.5 = -19.62454379 x = -19.62454379 Simplifying x = -19.62454379Solution
The solution to the problem is based on the solutions from the subproblems. x = {14.62454379, -19.62454379}
