Simplifying x(x + 3) = 330 Reorder the terms: x(3 + x) = 330 (3 * x + x * x) = 330 (3x + x2) = 330 Solving 3x + x2 = 330 Solving for variable 'x'. Reorder the terms: -330 + 3x + x2 = 330 + -330 Combine like terms: 330 + -330 = 0 -330 + 3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '330' to each side of the equation. -330 + 3x + 330 + x2 = 0 + 330 Reorder the terms: -330 + 330 + 3x + x2 = 0 + 330 Combine like terms: -330 + 330 = 0 0 + 3x + x2 = 0 + 330 3x + x2 = 0 + 330 Combine like terms: 0 + 330 = 330 3x + x2 = 330 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 = 330 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 330 + 2.25 Combine like terms: 330 + 2.25 = 332.25 2.25 + 3x + x2 = 332.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 332.25 Calculate the square root of the right side: 18.227726134 Break this problem into two subproblems by setting (x + 1.5) equal to 18.227726134 and -18.227726134.Subproblem 1
x + 1.5 = 18.227726134 Simplifying x + 1.5 = 18.227726134 Reorder the terms: 1.5 + x = 18.227726134 Solving 1.5 + x = 18.227726134 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 = 18.227726134 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 18.227726134 + -1.5 x = 18.227726134 + -1.5 Combine like terms: 18.227726134 + -1.5 = 16.727726134 x = 16.727726134 Simplifying x = 16.727726134Subproblem 2
x + 1.5 = -18.227726134 Simplifying x + 1.5 = -18.227726134 Reorder the terms: 1.5 + x = -18.227726134 Solving 1.5 + x = -18.227726134 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 = -18.227726134 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -18.227726134 + -1.5 x = -18.227726134 + -1.5 Combine like terms: -18.227726134 + -1.5 = -19.727726134 x = -19.727726134 Simplifying x = -19.727726134Solution
The solution to the problem is based on the solutions from the subproblems. x = {16.727726134, -19.727726134}
