Simplifying x(x + 3) = 511 Reorder the terms: x(3 + x) = 511 (3 * x + x * x) = 511 (3x + x2) = 511 Solving 3x + x2 = 511 Solving for variable 'x'. Reorder the terms: -511 + 3x + x2 = 511 + -511 Combine like terms: 511 + -511 = 0 -511 + 3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '511' to each side of the equation. -511 + 3x + 511 + x2 = 0 + 511 Reorder the terms: -511 + 511 + 3x + x2 = 0 + 511 Combine like terms: -511 + 511 = 0 0 + 3x + x2 = 0 + 511 3x + x2 = 0 + 511 Combine like terms: 0 + 511 = 511 3x + x2 = 511 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = 511 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 511 + 2.25 Combine like terms: 511 + 2.25 = 513.25 2.25 + 3x + x2 = 513.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 513.25 Calculate the square root of the right side: 22.655021518 Break this problem into two subproblems by setting (x + 1.5) equal to 22.655021518 and -22.655021518.Subproblem 1
x + 1.5 = 22.655021518 Simplifying x + 1.5 = 22.655021518 Reorder the terms: 1.5 + x = 22.655021518 Solving 1.5 + x = 22.655021518 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = 22.655021518 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 22.655021518 + -1.5 x = 22.655021518 + -1.5 Combine like terms: 22.655021518 + -1.5 = 21.155021518 x = 21.155021518 Simplifying x = 21.155021518Subproblem 2
x + 1.5 = -22.655021518 Simplifying x + 1.5 = -22.655021518 Reorder the terms: 1.5 + x = -22.655021518 Solving 1.5 + x = -22.655021518 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = -22.655021518 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -22.655021518 + -1.5 x = -22.655021518 + -1.5 Combine like terms: -22.655021518 + -1.5 = -24.155021518 x = -24.155021518 Simplifying x = -24.155021518Solution
The solution to the problem is based on the solutions from the subproblems. x = {21.155021518, -24.155021518}
